Hello!
im new to facebook api and i have a litle problem.. i created iframe app and im using the folowing code to invite my friends. invitation screen renders and im able to send invitation. when someone accepts invitation it redirects them to the following link:
http://www.facebook.com/reqs.php#!//apps.facebook.com/erste_app/
and nothing happens (only the facebook header apears and thats all)...when they manualy repost that link they are redirected to app and everything works...
