the actual threadid (my test db only has one thread right now, so it's 1).

ETA: Here's what I tested:

PHP Code:

require_once('global.php');

$editthreaddm =& datamanager_init('Thread', $vbulletin, ERRTYPE_STANDARD, 'threadpost');
$threadid = 1;
$threadinfo = fetch_threadinfo($threadid);
$editthreaddm->set_existing($threadinfo);
        
$newtitle = "New title $datenow"; 
$editthreaddm->set('title', $newtitle);
$editthreaddm->save();
