Since 3 days, every time I open the message moderation page of the Google Group I administrate, I can see this message:
Unable to load pending messages for moderation
Usually this page would list the messages from new users that are awaiting approval.
The window title tells me that there are 15 messages awaiting, and the number keeps growing, but I can not moderate.
Using the mobile version to access http://groups.google.com/group/anki-android/pendmsg is worse: it just shows the Google Groups homepage.
The error message is unknown by Google Search, so I guess few groups have seen this problem.
Another moderator of the group told me he has the same problem, though.
QUESTION: How should I report this to Google?
I could not find a help forum nor an issue tracker, nor a feedback form.
