Registration Issues

[Amaury]

I just had to create an account for someone who couldn't register. What could the issue be?

This is the error:

Warning: require_once(includes/functions_vbsfs.php) [function.require-once]: failed to open stream: No such file or directory in [path]/register.php(338) : eval()'d code on line 3

Fatal error: require_once() [function.require]: Failed opening required 'includes/functions_vbsfs.php' (include_path='.:/usr/share/pear') in /home3/khmediaf/public_html/register.php(338) : eval()'d code on line 3

You have a mod installed that's missing a required file (Maybe this one?: www.vbulletin.org/forum/showthread.php?t=176481).
