Maybe the leftover from the permissions prior to the update/disabling. I first noticed extension throwing an error when a moderator without mod permission for certain forum tries to moderate it redirects to main page. Current issue is that people are unable to view other people posts from the profile. It redirects them to main page if forum is a folder on the webserver. When said extension is disabled there are no such issues. If forum is in the public root it throws an sql error however.

You would have a bunch of people standing around in a cave, chatting and socializing and not getting anything done."
