To be honest most of these problems happens during the net soft updating. So, it seems that it is the reason but not the server issue. Of course the forum script should have been updated long time ago in order to be running properly. But the Mods can't do that themself. It's a matter of the access to all optiions of the server CP and the vBulletin license that is kept by the site owner. Be sure that what can be done by Mods it is done.
