Attention M1th.

PHP Code:

$forumids = array_keys($forumcache);
foreach($forumids AS $key => $value)
{
    $fperms = &$bbuserinfo['forumpermissions']["$forumid"];
    $forum = &$forumcache["$forumid"];
    if (!($fperms && CANVIEW) OR !($fperms && CANSEARCH) OR !verify_forum_password($forumid, $forum['password'], false)) {
        unset($forumids["$key"]);
    }
} 


$forumids apparently ends up empty, because when the script tries to implode() it later on for use in the IN() in the query, nothing results, breaking the query.
