well hardcoding the forum path is not the problem, I've done everything exactly as the readme says and it doesn't work.

I've tried hardcoding the forum path here:
require_once($vwd . '/includes/class_bbcode.php');

and that brings up the error related to hook system; my hook system on the forum is on.

When I try hardcoding the URL here:
chdir($_SERVER['DOCUMENT_ROOT'] . get_option('vbb_VBRPATH'));
//chdir('/home/mysite/www/forums');

I've tried both ways, still error shows.

The error is occurring because of this part of the code:
<?php
### Vbridge Call
$vbridge = Comment_Handler($post->ID);
###
?>

The comments code does not cause any error as I have that loaded right now without the vbridge call.
