Forum Database error
 

I took the Default Usergroup "Administrators" and renamed it. I then created another usergroup modeled after it, named it "Administrators" and took the Admins that were in the original default "Administrators" group and put them into the new Admin group. I decided later to do away with the second admin group and put things back the way they were so I deleted the "new" Admin usergroup and renamed the default group back to the original "Administrators". Now, when I move a user to that group I get the following error:

The funny thing is that they are added to the group though. Obviously I screwed something up - how can I fix it? Thanks.
