My fault, I'm not being clear enough. I can guarantee that all data is in the backup when it is restored. You can actually access the forums and all the data is there. However, when the administrator account logs on and clicks on any forum, it completely deletes all posts in that forum. I've tried everything that I know to try (checking the script paths and all the internals like that), but no matter what I do, or how many restores I do on the database, everytime the administrator clicks on a forum, all posts in that forum are deleted.
The only saving grace is that it works fine for regular users...

Thanks for your help. If you have any more ideas, I'm all ears.
