Don't have time to test this now, but I think he could do 1 of 2 things.
1. Enter an absolute path for the admin/config.php in the global.php file, ie /home/kinedac/www/forums/admin/config.php or something to that extent.
2. Change directory before including the file. Something like this:
PHP Code:
$curdir = getcwd ();
chdir ("/home/kinedac/www/forums");
include_once ("global.php");
chdir ($curdir);
I think the last one, if working, would be the cleanest way, since it does not involve editing a vbulletin file.
Again,
I have not tested this...
