Maybe server problems, or caused by some hacks or modifications you installed to your vBulletin. You can try replacing all of your vBulletin files with a fresh copy of it from the members area at vB.com

No one can solve it because we don't know what the problem is without having access to your server and files. It could be your server, or your forum files themselves.
