title: Graph Api Error Posting as page admin
body: <p>I'm developing an application in php using graph api.
  So, I have to post messages to a Facebook page as admin. I followed this: <a href="https://stackoverflow.com/questions/4385597/how-to-post-to-facebookpage-as-admin-via-api-php-sdk">How to post to Facebookpage as admin via API (Php SDK)?</a> .
  It worked well a couple of time, but now it returns this error:
   PHP Fatal error:  Uncaught GraphMethodException: Unsupported post request.\n  thrown in /home/redmarv/public_html/owl-test/facebook.php on line 453</p>
  
  <p>But can't find where the problem is. Even with google or search other posts right there.
  But I can't understand why it works a couple of time and then no.
  Without changing anything.</p>
  
  <p>Actually I use this code:</p>
  
  <pre><code>include_once "fbmain.php";
  
  echo 'Hi ' . $uid . '&lt;br /&gt;';
  
  $fb_accounts = $facebook-&gt;api('/me/accounts');
  
  $access_token = $fb_accounts['data'][1]['access_token'];
  
  echo 'Access Token= ' . $access_token;
  
  $facebook-&gt;api('/page_id/feed', 'post', array('message'=&gt;'OWL F TOOLS N TEST by: '.$uid,  'access_token'=&gt;$access_token, 'cb'=&gt;''));
  </code></pre>
  
  <p>The included fbmain.php does the session contro and create the $facebook object.
  Sorry for my bad English and thanks.</p>
