Not Found Cache not appearing on the Not Found map...

Wed, 06 May 2026 01:13:28 +0000

My new cache, GCBNVJ5, is as yet unlogged. Yet it has not yet appeared on the "Not Found Caches" map. Anyone know why? I'm pretty sure that in the past I could see my unfound caches on that map.

THANKS

Why is https://project-gc.com/Challenges/87689 recently producing an Error: Caught exception ?

Wed, 29 Apr 2026 16:49:51 +0000

Hi, I have used the 366-day-checker:

https://project-gc.com/Challenges/87689

for several months without any problems. However a couple of days ago I started getting the same error message whenever I intend to run it.

The script is started, runs for a few seconds and the breaks with Error Caught Exception.

Hope there is a timely fix for this.

Best Mi(chael)

P.S.: Error message now says: [string ""]:1396: attempt to index local 'badgegenV4' (a number value)

Bug? Event host count wrong

Mon, 27 Apr 2026 10:19:34 +0000

On PGC my diamond badge says I have 77 events hosted (and need 13 to go up a level)
At Geocaching.com I have

All Event Cache Types	81
Event Cache	36
Cache In Trash Out® Event	43
Community Celebration Event	2

I have one event in progress (held tomorrow, 28 April) which might allow for one error.

Why is there a 4-5 event discrepancy between PGC and GC? Is there a bug in PGC's event counting?

discrepancy in profile stats and needed found date tool

Wed, 22 Apr 2026 03:37:17 +0000

I appear to have a discrepancy between the profile statistics "Attended events by event date" and the Needed found dates tool. For May 30th, the profile statistics show that I NEED a regular event on that day when I filter for regular events. The Needed found dates tool shows that i DO NOT NEED a regular event on that day. I have manually reviewed a fresh my find PQ from GCHQ using GSAK and I do not have a regular event attended on May 30th.

Map counties shows counties as unfound while I do have founds in that county. How come?

Sat, 18 Apr 2026 20:22:00 +0000

Diekirch shows 0 founds.

But I do actually have found some caches in Diekirch, back in 2023.

And that is not the onliest county in Luxemburg that shows up as unfound, but I actually have found some.

Anybody an idea how come?

Thanks

Bug in profile stats page link

Wed, 08 Apr 2026 15:55:05 +0000

On the profile stats page, https://project-gc.com/Statistics/ProfileStats, there is a link stating "Permanent link to this profile." When I click the link, it takes me to https://project-gc.com/ProfileStats/Optimist+on+the+run which returns the error "This profile does not exist."

The URL should not have the + signs in it.

UPDATE: Found Issue: Not currently able to map unfound caches when looking at county maps

Sat, 28 Mar 2026 21:04:59 +0000

The issue was that "exclude unfound" was checked, which meant it wasn't showing any unfound caches. Don't remember checking that, but unchecking it fixed the issue.

No caches are showing up when I go to map unfound caches while looking in the "Map Counties" section. I'm a paid member and logged in.

Maximum number of lists reached.

Sun, 22 Mar 2026 17:51:06 +0000

Hello

I get this when I try to make another list. I had allot more than 100 but i deleted many so I now have only 86 but I still get that message.

Some owner in thee ownerstatistic are declared as unknown!

Project-GC UserScript display menu under Geocaching.com banner

Fri, 20 Mar 2026 16:28:02 +0000

Hello, I am using Firefox browser (latest version), installed greasemonkey and the Project-GC Userscript. Currently the menu is being displayed under the banner on the Geocaching.com website. Tried this on a different computer with Edge and Tampermonkey and its doing the same. What could be causing this? Is there a fix? I have an image but not sure how to attach it.

Virtual GPS Map issue? Using the selection tool to select caches, it looks like it removes caches but it is not

Thu, 19 Mar 2026 20:57:42 +0000

I'm in the virtual GPS map view. I want to select multiple geocaches to remove from my virtual GPS. I circle the caches with the tool, click remove and it looks like it removes them viewing the map but the cache count on the Virtual GPS stays the same. And when I refresh the map they are still in the virtual GPS map and the Virtual GPS.

I have screen shots, I'm not sure how to atttach them. It rejected me copying/pasting them here.

I can individually click each cache and choose to remove, that is working correctly. Its just the selecting tool that is not working.

360°: sectors displayed differently dependend on zoom factor

Wed, 11 Mar 2026 08:38:19 +0000

I noticed a issue on the 360°-from-home-map if the distance from home increases (tested at ~1000km).

You could see:

the sector is not covering the area of the caches (loaded by clicking the sector)
the same sector is shown on a different area by only using another zoom factor

Red markers are for orientation only and mark the same locations

Why isn't the county map allowing me to add (or remove) caches to (from) my virtual GPS?

Mon, 02 Mar 2026 19:28:55 +0000

I tried multiple counties, but this is where I first hit the glitch:

https://project-gc.com/Tools/MapCounties?post_crc_country=United+States&post_crc_county=Henry+County+%28IL%29&post_crc_region=Illinois&pre_crc_country=United+States&pre_crc_region=Illinois&pre_pr_profileName=javthrowr&submit=Filter

I was trying to add geocaches to my virtual GPS but it is not working (removing doesn't work either). I click on the cache, hit the virtual GPS button and nothing happens.

I can click on a cache, click on the coordinates which takes me to the live map and then add them. But from county maps, nothing.

I'm using Google Chrome, Version 145.0.7632.75 (Official Build) (64-bit).

I updated my Google Chrome to Version 145.0.7632.117 (Official Build) (64-bit) and I still have the issue.

Why aren’t my challenge caches showing as completed on Project‑GC?

Wed, 18 Feb 2026 15:45:45 +0000

I use Project‑GC to track my geocaching stats and check challenge caches, and but some challenges that don’t show as completed when even though I know I met the requirements. Im logged in with my account and I can see other stats fine.

I even tried refreshing the data and waiting a couple of days the FAQ says data can take a while to update, but it still shows “not completed” for challenges I definitely fulfilled. :contentReference[oaicite:0]{index=0}

I run a fast Kolkata Fatafat (FF) geocaching route tracker on the side and it updates quickly, so I’m wondering if I’m missing a step on Project‑GC or if there’s some trick to force a proper challenge check. Any ideas on what might be going wrong or how to fix it?

Virtual GPS - Delete List button doesn't work in Chrome

Wed, 18 Feb 2026 13:08:35 +0000

I am trying to delete a Virtual GPS list. I click 'Delete' then in asks if I am sure. I click 'Yes' and nothing happens. I have tried it in Chrome and Edge. This used to work, but stopped working a few months ago.

App updates/glitches

Sat, 14 Feb 2026 23:20:22 +0000

With the app/map updates over the past several weeks, I've noticed several glitches. Was hoping they would resolve, but not yet.

1) Lists do not sync properly between the website and the app. Specifically, deleted caches within a list, as well as entire deleted lists themselves continue to show up in the app, and when I manually delete them one by one in the app, I get a message that they've already been deleted...(Yes, I know! That's why I'm confused why they're still showing up!) This happens whether the list was downloaded for offline use or not.

2) When downloading lists for offline use, the prompt "you're using data" comes up, but the "continue" option does not work. You have to exit out of that and try a second time. It consistently works the second time, but not the first.

3) I used to be able to "add all" caches visible on the map to a list (a very useful tool, thank you!) This no longer works unless it's the very first thing you do when you open the app; it's as if this function is disabled after you've looked at any cache.

Can any of these functionalities be fixed? Thank you in advance.

Log written in Greek not showing as words

Thu, 12 Feb 2026 09:16:49 +0000

To fit the theme of the cache, I wrote this log in Greek (using Google Translate). However it's now appearing in my stats as my shortest log, with zero words. I presume this is related to this previous question. Are Greek characters not being recognised?

Extremes by category - new table

Mon, 09 Feb 2026 09:00:02 +0000

The new table for extremes is fun and i am glade that it's there, but it's the only one on the site i know about, that have green background behind zeros (not blank). know it is really minor thing but ... is there any better option to let you know?

Top Finders Slovakia/area not working

Sat, 07 Feb 2026 05:44:19 +0000

Hello, Top Finders Slovakia/area not working also as Czech/area.

Challenge checkers - new display kind of tooo large?

Thu, 05 Feb 2026 09:01:19 +0000

As of the rewriting of the Stats some effects are showing a strange behaviour on some challenge checkers.

For example: https://project-gc.com/Challenges/GCAFDJQ/81866

It runs as good as before, but any icon at the start of a row seems to be min. 4 times the size it was before.

I can provide a screenshot of how the result of that particular checker was before.
Tried on different PCs with different browsers and different sizing of the browsers etc.

Edit : Another example where things are mixed up. https://project-gc.com/Challenges/GC8EY7F/45867 all icons seem normal except for the favorites

Edit 10.02.2026 : just checked the mentioned checkers again. Those with the attributes are fine now. The last added one with the favorite icons is still off.... and the icons behind the checker https://project-gc.com/Challenges//101368 as well

Wieso werden bereits geloggte aber noch nicht erfüllte/ nachträglich erfüllte Challenges nicht mehr angezeigt?

Sun, 01 Feb 2026 17:10:52 +0000

Ich kann nicht mehr sehen, welche Challenges ich bereits geloggt hatte, aber noch nicht erfüllt hatte, ebenso wenig sehe ich , ob ich mittlerweile die ein oder andere erfüllt habe. Das ist mit das wichtigste Feature hier... was ist da los?

Danke euch vorab

My Project-GC dynamic html not updating on my gc.com profile page

Thu, 22 Jan 2026 04:45:07 +0000

My dynamic html is showing data from three days ago. I've recopied the html and reentered the html into my geocaching.com profile and it still is stale. I've checked in on various browsers and on a couple of OS and all showing the data from January 18. Is there a bug on Project-GC?

Bugs in translation / Fehler bei der Übersetzung / Fouten bij de vertaling

Thu, 15 Jan 2026 11:49:07 +0000

Hello, moin en hoi!

Probably since the solution for this bug two days ago somethings a wee bit fishy for translations. Most phrases are fine translated in different languages (I tried German and Dutch, the two I speak, and had a look at Italian), but some are not, especially headlines. Not everywhere, bur a bit erratic somewhere.

As German is my native language, I'll provide the details for that one:

Funde (Finds):

The header is English, all three lines
Finds by difficulty and by terrain have English headlines, but German Text
Mittlere Schwierigkeit und Terrain pro Jahr has German headlines, but Average instead of Durchschnitt in the column header
Finds by year placed is English, but the column headers are German
Funde nach Entfernung has Distance instead of Entfernung
The title of the matrix is English, the 3 lines underneath as well, but the descriptions at the matrix are German
In the Weg zur 81er Matrix the line underneath is in English
Höchste und niedrigste Erhebung has one German, one English line underneath.
Lot's other stuff alike, I fail to see any pattern

Events:

Titel lines are:
Saenger hat 327 Events besucht,
on 304 distinct dates und in 2 distinct countries
thus two different languages
In the Diverse Statistiken the names per line are in German, the values in English

And so forth. It's a bit weird, it's no problem for me, as I can read English, but perhaps for those not so fluent in English.

2 unterschiedliche Ergebnisse zur Multi-Matrix

Wed, 14 Jan 2026 13:05:33 +0000

Hallo,

ich habe 2 unterschiedliche Angaben zum Stand meiner Multi-Matrix.

Laut Checker fehlen mir noch 2 Wertungen. Nach dem DT-Matrix-Tool angeblich 3. Interessant ist auch das die Zeilen- und Spaltensummen unterschiedlich sind. Ich meine mich zu erinnern, das im D/T-Matrix-Tool schon mal 2 fehlende Wertungen gestanden hatten...

Viele Grüße Alex

Map Compare with multiple people breaks when changing geocache filters?

Tue, 13 Jan 2026 21:42:09 +0000

I'm trying to do a map compare with 4 other people. I set up the top with the other geocacher names. Then I go to add the criteria (counties, types, sizes) and after I hit submit it has reset the people I'm comparing to and only keeps the first person added. I have to go back in and add the additional people again to get the compare to work as needed.

As I'm attempting to do this again to document this for this post, now its not working at all. Even when I don't change the geocaching criteria in the second section and I go add the geocachers back and hit submit, its removing everyone but the first person I added

What is going on with the stats? I can't see my badges and my souvenirs.

Mon, 12 Jan 2026 14:25:52 +0000

Somehow my founds from yesterday haven't mad it in my stats, though I'm a paying member, and the folders for maps, challenges, badges, souvenirs and Lab-Caches are not shown at all, I just see my normal stats in that folder.

It's happening on my computer here (Win11/Edge) as well as on my Fairphone (Android 15/DuckDuckGo), so it's probably not something with my setup here.

Zweiter und falscher Challenge-Checker im Listing hinzugefügt.

Fri, 09 Jan 2026 13:50:44 +0000

Im Listing von GCABDQ5 wird durch das Project-GC Add-on der Challengechecker 79391 auch aufgeführt. Dieser gehört da aber nicht hin. Warum ist das so?
In der Liste mit den nicht erfüllten Challenges ist dieser zweite, falsche Checker auch aufgelistet.

Probably bug in dynamic notifications

Mon, 05 Jan 2026 17:57:16 +0000

I use the iOS app „cache notifier“ which works quite nice. Now I am on holiday and I get notifications from home.

It seems like PGC inserts my home coordinates. cache notifier shows the correct coordinates. If I the. turn off cache notifier and turn it on again, PGC shows the correct coordinates.

My founds in Colombia are not registered in Project-GC

Sat, 03 Jan 2026 11:01:19 +0000

In 2020 I was in Cartagena in Colombia and found three caches, two Traditionals and one EarthCache. But they are all not shown or registrated here, but on the HP of G$.

Is it a bug?

Why has "LOG COMPARE" no result?

A month ago it was worked.

possible minor "bug": "region" at Map Counties page

Mon, 29 Dec 2025 09:34:44 +0000

Don' know if this can by called a "bug", but on the Map Counties page below the map is the list of them; and the columns are labeled as regions. In Czech version this is labled "kraje" (regions) not "okresy" (counties) and the same is in English so i guess that it is not translation error but something different (?). Know this is minor problem but ...

A CCE from Oct 8 appears on my "found event grid" but similar from 5 Dec is blank

Fri, 19 Dec 2025 01:18:51 +0000

I attended a CCE on 8th October and it is on my found grid but similar CCE on 5th December is still blank - could this be a bug?

Also ; Is a HQ Block Party considered to be an Event for the my finds grid? (16th August is missing for me)

Invalid state

Tue, 09 Dec 2025 22:06:29 +0000

Lately, when I click on the link on a cache page (on my iPhone), it always asks for authentication. After I go through all the steps to reauthenticate, it gives me a blank screen with a tiny font saying Invalid state. This didn't used to happen.

Extremes by area - error in Austria

Thu, 27 Nov 2025 06:41:47 +0000

Extremes by area - error in Austria - The system does not show that I had found the northernmost cache in AT, despite it is correctly indicated that I have the northernmost cache in Bezirk Gmünd, which is the northernmost Austrian Bezirk.

MapCompare no longer working when comparing with myself

Tue, 11 Nov 2025 19:17:58 +0000

As the live map does not have any VGPS controls, where I can select a polygon area and add all the caches in the area to the VGPS, I used the "workaround" to do a map compare with myself, this way I could use the VGPS tools.

This no longer works - the following error messages come up:
Biesmugga’s privacy settings forbid this.
The player-'Compare profile name' and geocache-'Show' filters are required.

Comparing myself with myself should work, and it should also work with my friends, even if my profile is not publicly open, but open to my friends.

Why to open GC profile to public, to show my private data within PGC?

Tue, 11 Nov 2025 15:53:13 +0000

I'm confused, a change today (11.11.25) - I do not know PGC or GC
made PGC unusable for myself.

e.g. i cant use

challenges checkers for myself

D/T Matrix check for myself

Challenge checkers for myself

etc.

Privacy settings should so my understanding prevent others to see the protected data.

but why this is no preventing me to see my data myself?

this confuses me know a lot ...

in addtion i would also ask that friends are also should be able to see my data if i allow that ,,,,

Top Hidden Month Loggers - 2 bugs

Sat, 20 Sep 2025 11:03:40 +0000

hi,

i randomly checked top hidden month loggers in my country (Slovakia) with published dates between 2001-01-01 and 2001-12-31 and there seems to be some bugs:

- 2 players has 13 months in that year

- i have only 11, although i have all of them

New Cache notifier: County selecteion not showing counties if region selected

Fri, 05 Sep 2025 10:55:21 +0000

When creating a new cache notifier, the counties wont show if a region is selected. They do get loaded, but are not shown in the dropdown.

If no region is selected the counties are shown and selectable.

Event notifiers failing with Error Code 3

Tue, 02 Sep 2025 14:33:07 +0000

Hi, I am trying to create a new event notifier (for the entire Isle of Man), but I get an "Save failed, redirecting you back in 3 seconds" error message (sometimes but not always with an Error Code of 3).

I have tried this on different devices (Windows desktop, Apple desktop, and Android phone) and different browsers (Firefox, Chrome, and Safari) with the same result. The form is of course quite simple so I am pretty sure I am filling it out correctly (and I have another notifier for events in another entire country that works fine). In total I have 4 other notifiers, and I assume that a 5th one does not cross an unstated limit.

Any thoughts? Thanks, bejs

Caches don't appear. Why?

Mon, 01 Sep 2025 20:53:38 +0000

Bug: Statistics > Map Hidden Date ignores filter?

Sat, 30 Aug 2025 21:08:02 +0000

When I look at the Seagnoid's profile find stats it show he am missing eleven hidden dates for cache type=unknown.

However when looking at Statistics > Map > Hidden Date (https://project-gc.com/Tools/MapHiddenDate?pre_pr_profileName=the+Seagnoid&post_crc_country=New+Zealand&post_ts_type%5B%5D=Unknown+Cache&submit=Filter)

it shows no hidden dates. I suspect the query is accidentally ignoring filters.

Can't view archived events?

Fri, 29 Aug 2025 08:13:33 +0000

Recently discovered that it is no longer possible to find or see archived events on the map? Tried several different filter settings, but nothing helps. Can't see either the events you have attended or the ones you missed. Is this a bug or am I doing something wrong?
