I'm facing this problem:

Warning: require_once(./global.php) [function.require-once]: failed to open stream: No such file or directory in /home/xxxx/public_html/steroidpedia.com/includes/AuthPlugin_vbMediaWiki.php on line 49

Fatal error: require_once() [function.require]: Failed opening required './global.php' (include_path='/home/xxxx/public_html/steroidpedia.com:/home/xxxx/public_html/steroidpedia.com/includes:/home/xxxx/public_html/steroidpedia.com/languages:.:/usr/lib/php:/usr/local/lib/php') in /home/xxxx/public_html/steroidpedia.com/includes/AuthPlugin_vbMediaWiki.php on line 49

Domain: steroidpedia.com

MediaWiki Installed on main domain: steroidpedia.com
MediaWiki script version: 1.15.4 ( latest)

Vb Forums Installed on forums folder: steroidpedia.com/forums
Vbulletin version: 4.0.0 Patch Level 1
( Though I would like the forums on forums sub-domain)

Everything installed as said.

In Localsettings.php

define( 'VB_INSTALL_PATH', '../forums' );
require_once( "$IP/includes/AuthPlugin_vbMediaWiki.php" );

All files uploaded.

Product imported in Vbulletin Admin panel.

Also Navbar name + .. path given in Vb options.

Magic_quotes_gpc and other quotes etc are all off.

Please help me out. Did I missed anything ?.
