title: Facebook Graph API returns no content (empty data array)
body: <p>I'm using Python's <code>requests</code> to extract data from Facebook pages using Facebook Graph API as follows -</p>
  
  <pre><code>r = requests.request("GET", "https://graph.facebook.com/VisaUnitedStates/feed", params={'until':1364423876, 'access_token':oath_access_token, 'limit':900})
  r.content
  '{"data":[]}'
  </code></pre>
  
  <p>But it returns an empty data array as seen above. Same query works fine in Facebook graph explorer, so there is no issue related to permissions (Also, I've added all the permissions to the access_token). What can be the problem here?</p>
  
  <p>I've seen many other similar questions, but nothing is helping me here.</p>
