whenever i try to post on my forums i get this error: Authorisation code mismatch. Are you accessing this function correctly? Please go back and try again.

Also log out doesn't work properly either: Your user ID could not be verified to log you out. This may have been because a malicious Javascript was attempting to log you out automatically. If you intended to logout, please click the Logout button at the top menu.

Please read the pinned posts above!

I had the same problem and it was resolved here.

Please remember before you do anything always back up your forums and themes also your database so if you make a mess it can be easily restored.
