Strange login behaviour and non-closing pop-up

Same problem for me. Popup doesn't close after login and shows a "page not found" error. After refreshing manually i'm logged in.
Any ideas to fix this problem?

I've seen the popup not close when the app is in sandbox mode, and you log in as someone without permission to test the app.

Also javascript is fragile. If you have any errors in any javascript it might prevent the rest of the javascript from running. The firebug console can be helpful in catching some errors. Also try disabling any modules which add javascript to the page, until you can determine which one causes a problem.

David, are you using the new Javascript SDk that facebook released?

I am also having this same problem, but when replacing "Drupal for Facebook" footer hook in fb.module with this new JavaScript code. Everything works great!

I can also get the login button below to work properly.
For some reason when using the "Drupal for Facebook" JavaScript it appears as an iFrame div, and has error that state "invalid api key"

<fb:login-button show-faces="true"></fb:login-button>

Below is the code I used to replace "Drupal for Facebook's" JavaScript.

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    FB.init({appId: 'your app id', status: true, cookie: true,
             xfbml: true});
  };
  (function() {
    var e = document.createElement('script'); e.async = true;
    e.src = document.location.protocol +
      '//connect.facebook.net/en_US/all.js';
    document.getElementById('fb-root').appendChild(e);
  }());
</script>

Hopefully this is helpful David, but I don't understand your module or the facebook API enough to be sure.

Yes the 3.x branch is using the same javascript libraries.

I don't recommend the change you suggest, chitownguy. For the modules to work correctly, you should use the fbAsyncInit() as defined in fb.js.

I suspect if you look at your firebug or chrome console windows, you'll see javascript errors that are the cause of your problems.
