  <p>I copied the token from here : face book.com/tools/access_token/</p>
  
  <p>I'm doing tests here: <a href="http://sistemasfox.com.br/enc/face/uploadtopage.php" rel="nofollow">http://sistemasfox.com.br/enc/face/uploadtopage.php</a></p>
  
  <p>Is necessary to make some configuration specified in the facebook application?</p>
  
  <p>Thank you.</p>
