I've read the manual and I can't figure this out.

#
1 of 7: Checking MediaWiki Installation

OK:
The MediaWiki Installation should be fine.
#
2 of 7: Checking vbMediaWiki Wiki Files upload

OK:
All "wiki_upload" files are in the right place.
#
3 of 7: Checking Forum Path

Warning: chdir() [function.chdir]: No such file or directory (errno 2) in /home/novociv1/public_html/wiki/mediawiki/includes/vbMediaWikiAuthPlugin.php on line 9

Fatal error: require_once() [function.require]: Failed opening required './global.php' (include_path='/home/novociv1/public_html/wiki/mediawiki:/home/novociv1/public_html/wiki/mediawiki/includes:/home/novociv1/public_html/wiki/mediawiki/languages:.:/usr/lib/php:/usr/local/lib/php') in /home/novociv1/public_html/wiki/mediawiki/includes/vbMediaWikiAuthPlugin.php on line 22

From my localsettings.php:

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

I've tried making the install path ../forums public_html/forums forums forums/ /forums none of them seems to work. I don't understand what I'm doing wrong, and the manual doesn't have any examples under "Here are some example configurations:"

Edit: When I remove the following lines from localsettings.php I can interact with the wiki perfectly fine, just not from the forums.

define( "VB_INSTALL_PATH", "<<placeholder>>" );
require_once( "$IP/includes/vbMediaWikiAuthPlugin.php" );

More things I've tried in <<placeholder>>:
