Fatal error: Invalid forum parenting setup. Contact vBulletin support. in /includes/adminfunctions.php on line 3164

I'm getting that error whenever I'm trying to delete, edit, move (moderation actions on threads / posts), and also when trying to edit permissions, titles, descriptions of forums/sections.

Line 3164 is basically the code to recalculates forum parent and child lists.

PHP Code:

// #############################################################################
/**
* Recalculates forum parent and child lists, then saves them back to the forum table
*/
function build_forum_genealogy()
{
    global $vbulletin;

    if (empty($vbulletin->forumcache))
    {
        return;
    }

    // build parent/child lists
    foreach ($vbulletin->forumcache AS $forumid => $forum)
    {
        // parent list
        $i = 0;
        $curid = $forumid;

        $vbulletin->forumcache["$forumid"]['parentlist'] = '';

        while ($curid != -1 AND $i++ < 1000)
        {
            if ($curid)
            {
                $vbulletin->forumcache["$forumid"]['parentlist'] .= $curid . ',';
                $curid = $vbulletin->forumcache["$curid"]['parentid'];
            }
            else
            {
                global $vbphrase;
                if (!isset($vbphrase['invalid_forum_parenting']))
                {
                    $vbphrase['invalid_forum_parenting'] = 'Invalid forum parenting setup. Contact vBulletin support.';
                }
                trigger_error($vbphrase['invalid_forum_parenting'], E_USER_ERROR);
            }
        }

        $vbulletin->forumcache["$forumid"]['parentlist'] .= '-1';

        // child list
        $vbulletin->forumcache["$forumid"]['childlist'] = $forumid;
        fetch_forum_child_list($forumid, $forumid);
        $vbulletin->forumcache["$forumid"]['childlist'] .= ',-1';
    }

    $parentsql = '';
    $childsql = '';
    foreach ($vbulletin->forumcache AS $forumid => $forum)
    {
        $parentsql .= "    WHEN $forumid THEN '$forum[parentlist]'
        ";
        $childsql .= "    WHEN $forumid THEN '$forum[childlist]'
        ";
    }

    $vbulletin->db->query_write("

                $childsql
                ELSE childlist
            END
    ");

I figured out the problem, somehow my forum was hacked, when I edited forums in "Forum Manager", Title, description.. everything showed as:

r3dsoldier her ++++ you alll usa + isreal and ....... contact irlande@live.ie

How is that possible though? v3.6.8 is not stable? and why its only showing in forum manager?
