title: Auto login facebook - FB.Event.subscribe auth.login doesn't work
body: <p>for some reason today my code for auto login for existed members broke.
  normally this code works perfect, after a check with firebug I saw that there is a problem finding 'auth.login' for some reason, and therefor the call for window.location.reload(); isn't working. (if I refresh manually then the member shows as connect properly,the problem is just the auto login before the session is open that need a page refresh)
  I also tried to see if the problem is only 'auto.login' and replaced it with 'auth.authResponseChange' when I did it the page kept on refreshing ... so I figure that problem is with 'auth.login' trigger.
  does anyone knows for a special reason or any change facebook made that could cause this problem?</p>

  <p>BTW,Here is A WORKING AGAIN code:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
      &lt;script&gt;
        window.fbAsyncInit = function() {
          FB.init({
                appId  : '&lt;?php =$APP_ID ?&gt;',
                status : true, // check login status
                cookie : true, // enable cookies to allow the server to access the session
                xfbml  : true,  // parse XFBML
                oauth  : true
          });
  
        // Additional initialization code here
          FB.Event.subscribe('auth.login', function(response) {
            window.location.reload();
          });
        };
        // Load the SDK Asynchronously
        (function(d){
           var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
           if (d.getElementById(id)) {return;}
           js = d.createElement('script'); js.id = id; js.async = true;
           js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
           ref.parentNode.insertBefore(js, ref);
         }(document));
      &lt;/script&gt;
