I have one group library (https://www.zotero.org/groups/6084373/abk_fdm/library) I can no longer access via zotero.org - while my other group libraries are still working fine.

error log nr: 712673707

Do you have any idea what I could do to fix this problem. I tried to delete this library, but can't even do that, due to the connetion error...

Thank you!
