D/T matrix of a specific cache type

Wed, 17 Jun 2026 15:55:57 +0000

I am wondering if there is a place I can see a d/t matrix of all the caches in a specific area for a specific type of cache.

For example. I would like to see the D/T matrix for all the challenge caches in Michigan.

Is that possible?

i cloned a checker, now i can't get it to open

Wed, 17 Jun 2026 12:59:48 +0000

I cloned a checker from GCBPHAV for my cache GCBRM81.

I copied the tag when the popup was on the screen, but when I search for it, I can't find it.

When I cloned it, it did not have challenge anywhere in the title or on the page, but was a mystery. I have added challenge on the page and to the title. What am I doing wrong?

This is the link that I copied

Paid member stats not refreshed since 29 May

Wed, 10 Jun 2026 09:14:04 +0000

Hi all, I'm a paid member but my stats are stuck at 29 May (or before). The tool on the stats page says "Using data up to 2026-06-09". On a couple of previous days I've also tried clicking the "Regenerate my statistics now" button with no resulting update. I wondered if it's to do with the recent chages to Settings at geocaching.com or if it's a problem at this end? Thank you for your time, elfre :-)

What's with SARCRZY?

Wed, 10 Jun 2026 08:46:00 +0000

I have a charter member checker, and someone reported that it did not pick up SARCRZY's hides. So I did some digging.

SARCRZY's profile id is 69108 but when I run PGC.ProfileName2Id it returns null, so the checker does not pick up their hides. In other areas on PGC's site SARCRZY is reported as an anonymous user.

Has PGC lost SARCRZY's profile id is is there something unusual about SARCRZY?

81 grid no longer complete?

Thu, 04 Jun 2026 15:05:44 +0000

Hello, I am wondering if there is a way to tell which cache was changed in the D/T rating to cause the new hole in my grid or perhaps my cache log was removed and I would like to determine if that is the case. thank you

366 year streak

I cannot find a challenge checker using UK finds only also where ALs do not count towards the challenge.

Is it possible to create this challenge?

Map of D/T grids per area

Tue, 02 Jun 2026 19:14:19 +0000

When I look at the tools already available under Statistics | General | Cache Stats, I see things like "Geocache types per area", "Geocache sizes per area", "FP per area", and "FP per D/T", but there is no such tool as "D/T per area".

I want to propose a new tool to visualize the number of complete D/T grids available in a specific area (country/region/county, depending on user's choice). It should be based not on finds of a particular user but on all active geocaches in that area. As a possible implementation, it could show a map in which regions are colored according to the maximal number of D/T matrices per country/region/county and showing the rarest D/T combinations for every country/region/county.

The practical use for such a tool would be, for example, to convince reviewers that enough caches exist in a given region to justify a D/T-matrix based challenge. If I want to publish a challenge to complete the D/T-matrix in a single county, seeing how many caches are available there for every D/T combination is currently impossible with the available tools. If this is implemented, one could also see in which regions a D/T matrix is possible to complete at all, and which specific combinations are missing.

At the moment I can do this for countries and regions by creating a Location filter in c:geo, but that works only for single D/T combinations, requiring a lot of manual work. It also doesn't work at all for counties because county is not included in the location field in c:geo.

Can the Checkers tell me the date I qualified?

Sun, 31 May 2026 21:40:16 +0000

I'm struggling to find the date I qualifed for each challenge. Separate of the checker, I've attempted using map compare and building a list of caches I have with the attribute in question however I cannot bring in date I found each cache to determine which date I actually qualified. Is there any easy way to just have the checker tell me the date? The issue is negative attributes, I can do the regular attributes using geocaching.com

Lua Checker for distance from home coordinates

Fri, 29 May 2026 09:01:11 +0000

Hallo,

I'm looking for a Lua-Checker to create a checker for me.

The cacher had to find caches in the different distances of the geocache-statistics, to solve the Challenge.

Would someone be so kind to help me?

Wrong challenge checker for GCB9PM3

Map Not Found Caches does not show unfound caches

Thu, 28 May 2026 07:20:52 +0000

I have several caches in Poland that have not yet been found. I noticed that they don't appear on the "Map Not Found Caches" in Project GC. Is this a bug or is there something I overlooked? Here is the list of GC codes that I can't see on the map: GCBQGK3, GCBN15X, GCBN15X, GCBN14D, GCBN147, GCBN13N, GCBN133, GCBN133, GCBN12D, GCBN121, GCBN10Y, GCBN10Q, GCBN10D, GCBN0ZT.

Coordonate in personnal note became corrected coordonate

Tue, 19 May 2026 21:58:24 +0000

In my personnal note in geocaching, I put some coordinate as a try. When I create a virtual gps table, I find out that those coordonates appear as corrected coordonate but it is not the case. I get pictures but I don't see how I can sent them.

Basic member owners can't verify Challenge checkers with PolyChecker because of Premium caches

Sun, 17 May 2026 23:14:57 +0000

I have a challenge cache where you have to find caches in certain map regions. The challenge checker uses the genericPolyChecker https://project-gc.com/Challenges/GC58381/18168.

I wanted to verify a cacher that logged my cache and saw, that when I use the checker with his name it shows the challenge as not fulfilled. With some cross reference and checking different users I found, that the checker won't show a region as fullfilled, if there only was a premium cache found, as I am only Basic member. I am pretty sure, that worked before.

Since basic members can log premium caches, this seems off and especially as I am the owner of the cache and I wanted to verify a log.

GCBQ5N4 - checker for HIDDEN geocaches in foreign countries

Sun, 17 May 2026 22:00:47 +0000

I need a challenge checker for getting a result of hidden geocaches by a user NOT in his own country. Example, I am german and hided already geocaches in more than 5 countries. I want to create a challenge Geocache which request for example 2 or 3 foreign countries of the owner where he/she has already HIDDEN a geocache (events and LABs should NOT be accepted, ECs are ok)

Could you please write me such a challenge checker?

Issues sharing virtual gps with other paid members

Fri, 15 May 2026 18:54:10 +0000

I shared my virtual gps with a friend, he got the "conversation" that it was shared with him, but when he goes to view it by clicking on the link it gives him a completely different virtual gps with a different name and I don't have any virtual gps' with that name. He sent me a video showing me this weird issue, I could try to share if that would be helpful. And now I just had another friend tell me the same exact thing happened to her - a mutual friend shared a virutal gps with both of us. I had no issues getting to it and seeing it, but she could not get to it.

A follow up, I just went to a recent "conversation" and clicked on the link, it took me to a completely different virtual gps than the one in the shared "conversation". Tried again with a different "conversation" and it took me to the previous conversation's link. Its like the links do not match up with the conversations? Went to another older "conversation" and it also took me to a completely different virtual gps than the one it should have been tied to.

Let me know how I can help solve this issue.

An additional side note but it may be related, when I'm in virtual gps and I switch to a different virtual gps, the virtual gps up on the bar across the top of the page does not update to the new virtual gps I'm sitting on unless I refresh the page. I'll try to attach a photo, but I think I had issues doing so last time.

An update has removed the project-GC link that adds county info to cache pages. how do I get it back?

Tabs have moved around

Wed, 13 May 2026 16:36:14 +0000

I have just noted that my 'Hides' Tab has moved along to 8th tab from the left when it was 4th on my profile stats page
Was there a reason for moving this - is there a way to put it back where it was before

Thanks

How do I find caches that I found that are archived

Wed, 13 May 2026 12:54:56 +0000

Map Compare will only show map, when the amound of caches are below 1500 (Milan Area)

Tue, 12 May 2026 16:04:21 +0000

Map-Compare will only show map, when the amound of caches are below 1500, when the amound is above 1500 the map area doesn't show anything (No map, or message).

Edit: This seems to be only in the milan area, due to an unusual cachename

The cachelist below the map area does show

Example 24km Milan

Example 25km Milan

Typo in image titles for 2 attributes

Mon, 11 May 2026 19:22:10 +0000

In user profile stats page, https://project-gc.com/Profile/ProfileStats , in the last attributes section, among the negative attributes in the first table row there are attributes for:

Not a long hike ... what is above and greater than 10km , but image HTML title writes <10km
Not a medium hike ... what is less than 10km , but image HTML title writes >10km

But title for the images in the ProfileStats page has angle brackets (signs < and > ) is the opposite logic.

Screen shot of the image titles with the opposite angle brackets sign in the code: https://ibb.co/r2rBW2S8

Ich habe keine Möglichkeit Checks durchzuführen, da irgend eine Einstellung gesetzt ist, welche dies unterbindet.

Sun, 10 May 2026 12:31:36 +0000

Irgendwann habe ich mal an meinem Profil etwas angepasst und mich mal durch die Einstellungen geklickt.

Irgendwie muss ich etwas aktiviert haben, dass ich mich selbst und andere Personen nicht mehr Checken kann, also so gar nicht.

In den Privatsphäre Einstellungen ist der Haken bei "Meine Statistiken vor anderen komplett verbergen" aktiviert. Diesen entferne ich und Speichere weiter unten aber die Änderung wird nicht übernommen. Der Haken bleibt.

Irgendwie habe ich das Gefühl da liegt noch eine Einstellung weiter drüber, welches das erzwingt aber bisher konnte ich nicht fündig werden.

Auch die rote Meldung "Deine Statistiken sind für andere nicht sichtbar!" steht permanent da und diese bekomme ich nicht weg.

Kann hierbei jemand helfen?

Vielen Dank im Voraus:)

Think the checker for GC5BF5 is ignoring (at least)Virtuals and Earthcaches

Sun, 10 May 2026 00:42:51 +0000

I just ran the checker for the Cache Across Utah (Challenge Cache) and it only shows that I have 6 of the 29 counties. But looking at my map, it shows 11 counties completed. It appears the checker is ignoring Earthcaches and Virtual (not sure what else). The cache page descriptions states " ... Visit a cache in each of Utah's 29 counties. Any cache, of any type and size is good, as long as it is physically located within the county boundaries...."

Bug in extremes by area?

Sat, 09 May 2026 18:23:41 +0000

When I look into the "extremes by area" and look into the dropdown menu of Germany, I can see 15 of the 16 states. Bavaria/Bayern seems to be missing. I am sure that I have found caches there. Is it a bug?

81er Matrix in 2 verschiedenen Ländern

Wed, 06 May 2026 20:21:58 +0000

Hallo

Ich möchte eine Challenge legen und soweit habe ich auch alles fertig. Ich benötige noch den richtigen Checker. Es soll einmal die 81er Matrix in zwei verschiedenen Ländern erfüllt sein und das mit der Matrix auch angezeigt werden.

Im Prinzip wie bei GC9EHQR nur halt für 2 Länder

Mein GC-Code ist GCBPER5

Kann mir den Checker jemand bauen?

minor bug "Finds to May 6th for each year"

Wed, 06 May 2026 12:26:53 +0000

Hello there!

in English I see "Finds to May 6th for each year", but in Czech there is "Nálezy do %s května pro každý rok" (the number doesn't seem to work?) and in Slovak there are two dots (6.. insted of 6.): "Nálezy do 6.. mája v jednotlivých rokoch".

PS: why are half of the table/graph names in Hungarian and half of them English when if I select Hungarian as language?

PPS (not related to the main report): in the table "Finds by found date", the number one (1) is black while other numbers are white.

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

My stats are not showing correctly.

Mon, 04 May 2026 09:43:21 +0000

My most southerly is incorrect when another user checks my stats is shows correctly but on both my computer and phone I have it incorrect.

This should also give my lowest elevation as seen in a challenge check this morning

The cache that's not registering correctly is GC2PPNP

Project-gc via the macro "Geocaching.com + Project-GC" states that I have two logs registered on a cache.

Fri, 01 May 2026 14:15:14 +0000

The macro "Geocaching.com + Project-GC" tells that I have two logs on a cache thus the total number of caches differs from what GSAK reports. If I look at the cache I suspect is the cultprit I can only find one log.
However when I wrote a note to tell why I couldn't attend I managed to first post it as an attended log which I later changed to a "write note".

Is it possible fix this?

Suggestion to new statistics

Thu, 30 Apr 2026 10:23:16 +0000

I have a suggestion to a new statistics:

An overview of active caches in a region, placed by year and number of you have found of those.

It is already possible to have an overview by caches in a region or city and you can filter by active caches and a period when they were placed.

For example: you have a choicebox with country and region, and then the result is a table by year:

Year	Active caches	Found by user
2000	8	6
2001	19	12
2002	35	16
2003	48	22
...	...	...
2025	1105	805

The idea for this statistics is when a logged the oldest caches for a specific region. When i found all of them from 2000, i logged those from 2001,... so at the moment i have found all the caches in my region places between 2000-2010 and i want to log those from 2011 this year.

Map of challenge caches

Wed, 29 Apr 2026 20:12:12 +0000

Why is it that caches in Northern Ireland don't count as UK?

Wed, 29 Apr 2026 18:28:01 +0000

Hi,

I found some caches in Ireland and also some in Northern Ireland (Derry, to be precise). I was expecting to get credit for finding caches in the UK, but no country souvenir and no map entry. How come?
I'm aware that this is not a Project GC problem, it's the same in the Geocaching map, but I thought you might know.

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)

what happened to the "degrees from home" statistic?

I'm missing the degrees from home graphs (by number, by distance) in the Profile Stats. Is there any way to see this information?

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?

County boundary processing rules per country – seeking documentation

Fri, 24 Apr 2026 12:28:25 +0000

i Project-GC team,

I'm building a desktop app for geocaching challenge-checking that needs to assign caches to counties / regions in the same way Project-GC does. Thanks to Pleu's earlier answer (https://project-gc.com/?qa=30819) we already know that PGC uses **osm-boundaries.com, database `osm20210412`, admin_level 6** as the base, and that **UK has "many special rules and unions"** on top.

I downloaded the same source data and compared the raw feature count with what Project-GC shows in its statistics. Most countries differ – sometimes by a few features, sometimes drastically:

| Country | osm-boundaries (level 6 unless noted) | PGC shows | Δ |
|---------|----:|----:|----:|
| AT | 93 | ~94 | -1 |
| BE (level 8) | 581 | 565 | +16 |
| CH (level 8) | 2234 | ~2113 | +121 |
| CZ (level 7) | ? | 77 | ? |
| DE | 405 | 401 | +4 *(found: 1× church boundary + 3× historical Landkreise)* |
| FR | 131 | 96 | +35 *(overseas territories?)* |
| GB | 226 | 102 | +124 *(special rules per Pleu)* |
| HU (level 7) | 174 | 175 | -1 |
| IT | 102 | 107 | -5 |
| LU (level 8) | 102 | 102 | 0 ✅ |
| NL (level 8) | 354 | 342 | +12 |
| PL | 387 | 380 | +7 |
| SK (level 7) | ? | 79 | ? |

To match Project-GC exactly, I'd need to know per country:

1. **Which admin_level is used?** (We assume level 6 for most, but BE/CH/LU/NL=8, HU=7, etc. – is this correct?)
2. **What additional filtering is applied?** Examples for DE we found:
- Excluded: `Evangelische Landeskirche in Baden`, `Landkreis Bühl (historisch)`, `Landkreis Kehl`, `Landkreis Lahr` (the latter three were dissolved in 1973)
Are there similar exclusion lists for other countries?
3. **For UK specifically:** What "unions" are performed? E.g., is `Bristol` formed by merging multiple OSM boundaries? Is there a list of these unions?
4. **For FR:** Are overseas departments (DOM-TOM) included or excluded? Anything else?
5. **Is there any data file or documentation** that lists the exact set of regions used per country?

I'm happy to share my work back to the community. Goal is a stable, project-gc-compatible county lookup for offline use.

Thanks for any pointers!

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.

Profile does not exist

Mon, 20 Apr 2026 17:30:40 +0000

I have just come across something I have not seen before - putting in a cachers ID in the profile name box - to be met with a large yellow triangle with a big black exclamation mark and underneath This profile does not exist
I am aware that when cachers dont wish for their stats to be viewed they can select that option and the page comes up with the statement about opting out etc - but the above seems to suggest the cacher name is not recognised despite it being copied and pasted from the GC profile - is this a glitch or another option that cachers can select ?

This profile does not exist
