Yeah, it looks like a php version thing. You should really upgrade to the latest vbulletin release that's compatible with the php you have. But if you don't want to do that you can edit the vb files and replace all these:

PHP Code:

error_reporting(E_ALL & ~E_NOTICE); 


with this:

PHP Code:

error_reporting(E_ALL & ~E_NOTICE & ~8192); 


(hopefully using a program with a search and replace function, because there's a lot of those lines).
