I ran into a problem with the NavBar link to the Forum Rules; it breaks if you reference it outside of the forum, e.g. when using vBAdvanced.
Easy fix, include the BBURL in the NavBar link that's constructed on line 84:
PHP Code:
$cyb_frules_link .= '<a href="' . $vbulletin->options['bburl'] . '/misc.php?do=cfrules"';
Hope you can include this in the next version
