Thread:Project:Support desk/I can't remove usergroups from users

I recently updated MediaWiki from 1.17 to 1.18, if that could have caused any issues.

The error I got was:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "User::removeGroup". Database returned error "1146: Table 'ske1145307562847.mw_user_former_groups' doesn't exist  (ske1145307562847.db.7539804.hostedresource.com)".
