How to move thread and send PM simultaneously via Cron?
Move thread made with datamanager_init the same as send PM.

The Problem is PM doesn't send, only if run this Cron Task manually (press button in AdminCP).

The code like is something like this:

$check=$vbulletin->db->query_read(".........................");
while ($check2 = $vbulletin->db->fetch_array($check))
{	
  // Send PM
  $pm =& datamanager_init('PM', $vbulletin, ERRTYPE_ARRAY);
		$pm->set('fromuserid', 1);
		$pm->set('fromusername', 'system');
		$pm->set('title', 'lalala');
		$pm->set('dateline', TIMENOW);
	
		$threadlink = ' . '/showthread.php?t=' . $check2[threadid] . ']' . $check2[title] . '';
		$pm->set('message', construct_phrase($vbphrase['XXXXXXX'], $threadlink));
	
		$recipients = $check2[postusername];
		
		if ($recipients) {
	
			$pm->set_recipients($recipients, $botpermissions);
			if (!count($pm->errors)) $pm->save();
			
		}

  require_once('./includes/functions_databuild.php');		
  $threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
					
		$threadman->set_existing($check2);
		$threadman->set('forumid', $vbulletin->options['forumarchive']);
		$threadman->set('sticky', 0);
		$threadman->save();
		build_forum_counters($check2['forumid']);
		build_forum_counters($to);
			echo "Auto Move Threads:<i>".$check2[title]."</a></i><br>";
log_cron_action('Move thread and send PM', $nextitem);
}
