title: Facebook app - can't retrieve users Facebook post information
body: <p>We have a very important and urgent problem with our Facebook app. The app is a complicated competition where one of the "questions" is the possibility for the users to post a message to their wall. The app will then count how many LIKES this particular wall posts have gotten. </p>
  
  <p>So the users can enter a high score page where - for each user - the app will try go get the post info through a call like</p>
  
  <pre><code>https://graph.facebook.com/[USER_ID]?access_token=[TOKEN_ID]
  </code></pre>
  
  <p>The big problem is that for most users then the app cannot get the post-information. We just get a "Unsupported get request". For some users it works fine. I would say that around 20% is working ok.</p>
  
  <p>Some things to remember</p>
  
  <ul>
  <li>We ask for permission to READ_STREAM </li>
  <li>We have the users Facebook ID and the Facebook Post ID (for all
  entries - also those returning a "Unsupported.....") so all seems fine on our side.</li>
  </ul>
  
  <p>So what might be the problem here? We understand that there could be numerous issues like users blocking apps, private/public settings etc. - but it just seems very odd that around 80% of the users will have these settings. Have we forgotten anything or done anything wrong?</p>
  
  <p>If you have any insights on the above please let's hear them. We are getting pretty desperate as we have an inoperative highscore running at the moment and we wonder if it ever will work properly.</p>
  
  <p>Code Example:</p>
  
  <pre><code>$facebook = new Facebook(array(
          'appId' =&gt; $app_id,
          'secret' =&gt; $app_secret,
          'cookie' =&gt; true
      ));
  
  $accessToken = $facebook-&gt;getAccessToken();
  $facebook-&gt;setAccessToken($accessToken);
  $post = json_decode(file_get_contents('https://graph.facebook.com/'.$postid.'?access_token='.$accessToken), true);
  </code></pre>
  
  <p>Where <code>$postid</code> is the id of the FB post.*</p>
