In functions_showthread.php FIND

PHP Code:

static $gotrank, $sigcache, $checkperms, $postelement, $month, $day, $year, $counter; 


REPLACE that with

PHP Code:

static $gotrank, $sigcache, $checkperms, $postelement, $month, $day, $year, $counter, $gotpgroups; 


FIND

PHP Code:

// get rank 


ABOVE that ADD

PHP Code:

if (!$gotpgroups[$post['userid']])
{
    $membergroups = explode(',', $post['membergroupids']);
    foreach ($membergroups as $membergroupid)
    {
        $usergroup = $usergroupcache[$membergroupid];
        if ($usergroup['ispublicgroup'])
        {
            $pgroups[] = "<a href=\"profile.php?$session[sessionurl]do=joingroup&amp;usergroupid=$membergroupid\">$usergroup[title]</a>";
        }
    }
    if (is_array($pgroups))
    {    
        $post['pgroupstr'] = implode(',', $pgroups);
        $gotpgroups[$post['userid']] = $post['pgroupstr'];
    }
    else
    {
        $gotpgroups[$post['userid']] = '';

    }
}
else
{
    $post['pgroupstr'] = $gotpgroups[$post['userid']];

} 


Then you can use $post[pgroupstr] in Template postbit.
