Geogebra group application error
I've started a group two years ago. It was ok for about a year, but after that something crashed. Now in the group we can see Members, Resourses and Tasks – but we can't see Posts. Now if I or anybody else try to see Posts we see only this:
'An error occured: Application error' – and the empty page.
People still can join the group – I keep getting notifications. It lasts for several months.
The group is https://www.geogebra.org/gr...
The group code is TEJ9P
Please help me to fix the bug – there are many valuable materials and contacts in this group.
