Публикация на стене Facebook пользователя с использованием php 2011

На стену ничего не отправляется, выполнение прекращается после попытки $ result = $ facebook-> api ('/ me / feed /', 'post' , $ attachment);, любая идея, что не так.

$facebook = new Facebook(array(
  'appId'  => 'xxxxxxxxxxxx',
  'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
));

// Get User ID


$user = $facebook->getUser();
if ($user) {
  try {
    // Get the user profile data you have permission to view
    $user_profile = $facebook->api('/me');
    $uid = $facebook->getUser();


      $url = $facebook->getLoginUrl(array(
    'canvas' => 1,
    'fbconnect' => 0,
    'req_perms' => 'email,publish_stream,status_update,user_birthday,user_location,user_work_history'));


    $attachment = array
 (
 'access_token'=>$facebook->getAccessToken(),
 'message' => 'I had a question: should I write a PHP facebook app that actually worked?',
 'name' => 'I Asked Bert',
 'caption' => 'Bert replied:',
 'link' => 'http://apps.facebook.com/askbert/',
 'description' => 'NO',
 'picture' => 'http://www.facebookanswers.co.uk/img/misc/question.jpg'
 );
 echo "Test 1"; 

$result = $facebook->api('/me/feed/','post',$attachment);

    echo "Test 2"; 
    $_SESSION['userID'] = $uid;


  } catch (FacebookApiException $e) {
    $user = null;
  }
} else {
  die('Somethign Strange just happened <script>top.location.href="'.$facebook->getLoginUrl().'";</script>');
}
