double post.
for those that have been having problems, change your required shiznit to this
Code:
$vbulletin_root_path = 'http://www.THEFULLURLTOYOURSITE.com/vb';
include($vbulletin_root_path . '/global.php');
include($vbulletin_root_path . '/PluhConfig.php');
include($vbulletin_root_path . '/admin/config.php');
that's the full URL, worked for me (on other hacks.)
