Is your php file included (or "required") in another file, or is it supposed to be "stand-alone". I'm not sure if you're showing all the code in what you posted above, but if that file isn't being included in another vbulletin file, then you need to define some things before including global.php. If it is being included, then you probably don't need to include global.php.

Your original code had "error_reporting(0);" and some '@'s at the beginning of some function calls. You might want to remove those, at least temporarily, so you can see any PHP errors that you might be getting.
