if($_SESSION['USERID'] == "")
{
	$A = $config['FACEBOOK_APP_ID'];
	$B = $config['FACEBOOK_SECRET'];
	define('FACEBOOK_APP_ID', $A);
	define('FACEBOOK_SECRET', $B);
	$smarty->assign('FACEBOOK_APP_ID',$A);
	$smarty->assign('FACEBOOK_SECRET',$B);

	function get_facebook_cookie($app_id, $application_secret) {
	  $args = array();
	  parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
	  ksort($args);
	  $payload = '';
	  foreach ($args as $key => $value) {
		if ($key != 'sig') {
		  $payload .= $key . '=' . $value;

	  }
	  if (md5($payload . $application_secret) != $args['sig']) {

$conn->execute($query); is returning a non-object, probably FALSE.

You should check under what conditions that method would return FALSE.

Hello thank you for your reply! as my name says i am completely newbie so i dont really get what should i look for would it help if i attach the config file? or where should i look for this FALSE return?
