title: FB.logout doesn't log out
body: <p>I have implemented a Facebook based login.
  The FB.login works perfectly, but the <strong>FB.logout</strong> doesn't. I have tried with different FB.init, deleting cookies, running the logout page several times in a row, but the only way to log my user out is in facebook itself.</p>
  
  <p>The code I'm using for logout is:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script src="http://connect.facebook.net/en_US/all.js"&gt;&lt;/script&gt;
  &lt;script&gt;
  
    FB.init({
      appId: '***************',
      xfbml: true,
      status: true,
      cookie: true
    });
  
    FB.getLoginStatus();
  
    FB.logout();
  &lt;/script&gt;
  </code></pre>
  
  <p>Any ideas?
  Thank you</p>
