Fixed  Rebuild User Caches after deletion of user group...


Well-known member
I had a secondary usergroup from my old forum... I have deleted it on my new forum. However, it looks like the database has retained the secondary usergroup value. Now when I try to rebuild user caches I get the following error:

Server Error

I have discovered the issue... if you delete a usergroup, and a user has that usergroup listed as his primary usergroup, it will break.

I have fixed the code to prevent the listed error.

However, I can't reproduce the underlying issue. I can see the theory of it happening - the xf_user_group_relation table not having the correct data - but users are moved to a different primary group when the user group itself is deleted. We'd have to try to figure out why incorrect data is in that table in the first place.
