could you pls provide more details of your requests.
Running your two stats for country Germany I received data for the MD caching points but for Top image uploader I get an error (timeout) based on "external server did not deliver data in time limit".
Actual the geocaching.com servers have some problems, so maybe your problem is based on that.
So pls try again or give more specific queue request data, to find out if PGC or geocaching.com server are the problem.
