Paul, I think there is a major bug in permission calculation:

PHP Code:

if(intval($rex['fcpermissions']))
{
    $bit = 1;
    foreach($permlist as $permission)
    {
        if ($rex['fcpermissions'] & $bit) $GLOBALS['vbulletin'][$permission][] = $group;
        $bit *= 2;
    }
}
else
{
        exit('vBulletin 3.7 : Integration Error 03 : No permissions set for usergroup '.$group.'.');
} 


This causes any user who is a member of several usergroups to not being able to use the chat - unless all groups do have permissions > 0.

This is inconsistent behaviour, as all other usergroup permissions in vBulletin are additive, eg. if I have a permission in any of my membergroups I do have the permission, no matter if I do hve it in all of my membergroups or not.
