Facebook auth fails with white screen?!

Hi,

I am trying to authenticate my users over Facebook. I already used this feature in previous versions, so my Facebook App is already live and pre configured. Now I want to add this feature again and I tried everything like in the past version. This is what I've done until now:

1. Added on my tiapp.xml this property (with my app id): <property name="ti.facebook.appid">123456789</property>
2. Added in my Info.plist all the other required information like URLSchemes etc.
3. (Added the below code in my app.js)

   var fb = require('facebook');
   fb.appid = 123456789;
   fb.forceDialogAuth = true;
   fb.permissions = ['publish_action'];
    
   fb.addEventListener('login', function(e) {
       if (e.success) {
           Ti.App.fbAccessTokenFacebookSDK = fb.accessToken;
           Ti.API.info("Facebook access successfully authorized with AuthCode: " + Ti.App.fbAccessTokenFacebookSDK);
       } else if (e.error) {
           alert(e.error);
       }
   });
    
   if (!fb.loggedIn) {
       fb.authorize();
   }

   Unfortunately, the popup comes up but I just see a white screen (or nothing in there)?! http://i6.minus.com/jbhWiCbVYhrKpv.png

What am I doing wrong?

Thanks in advance, Alex
