look for

if ($lastposts['lastpost']) {
if ($lastposts['lastpost']>$lastpost or $lastposts['lastpost']<$currentlastpost) {
$lastposts=$DB_site->query_first("SELECT lastpost,lastposter FROM thread WHERE lastpost='$lastposts[lastpost]'");
$lastpost=$lastposts['lastpost'];
$lastposter=$lastposts['lastposter'];
}
}

change to

if ($lastposts['lastpost']) {
if ($lastposts['lastpost']>$lastpost or $lastposts['lastpost']<$currentlastpost) {
$lastposts=$DB_site->query_first("SELECT lastpost,lastposter,title FROM thread WHERE lastpost='$lastposts[lastpost]'");
$lastpost=$lastposts['lastpost'];
$lastposter=$lastposts['lastposter'];
$lasttitle=$lastposts['title'];
}
}

your looking for the above one if you still can't find it your looking for

$lastposts=$DB_site->query_first("SELECT lastpost,lastposter FROM thread WHERE lastpost='$lastposts[lastpost]'");
$lastpost=$lastposts['lastpost'];
$lastposter=$lastposts['lastposter'];
