During import of our users, it asked to merge mu user-account and admin account.
I made up a new name.
Import went well. Forum was up and running... *Yeeeee*
Advice by the script: check the (user-)permission.
So I did.
I also changed the super_moderator back to my original name.
Als tried to get the user to become 'super_moderator'. I do not want those rights on my user account...
Since then: Forum says: ERROR. You have no permissions to view this page.
This goed for my administrator account (which can not become super_moderator by the love of God) and my personal account (who is still super_moderator).
So: I now have a forum, which cannot be altered by any admin or moderator... W T F ?!
