title: Logout methods doesn't work
body: <p>I integrated FB regisration into a WP site. Test site is here: <a href="http://teszt.avea.hu/blog/" rel="nofollow">http://teszt.avea.hu/blog/</a>
  I can manage Registration user account merge/creation and Login well but I can't loguot FB users from FB so FB.getLoginStatus always remains 'connected'.
  I tried the following methods:</p>
  
  <ul>
  <li><strong>PHP SDK:</strong> <code>$facebook-&gt;getLogoutUrl();</code> generates a well formed URL (https, token, etc.). It redirects well, but <code>FB.getLoginStatus</code> remains <code>connected</code></li>
  <li><strong>JS SDK:</strong> <code>FB.logout(function(){ window.location = 'http://teszt.avea.hu/';});</code> doesn't log out the user.</li>
  <li><strong>Cookie solution:</strong> <code>$facebook-&gt;destroySession(); setcookie('fbs_'.$facebook-&gt;getAppId(), '', time()-100, '/', '.avea.hu');</code> also doesn't log out the user. I can create othes cookies, but can't replace FB cookie.</li>
  </ul>
  
  <p>I run out os ideas. Do you have any idea why can't manage logout? Is it a permission problem? </p>
