Infinite login loop on Facebook app using Javascript SDK

Question

I built an app based on one of the Facebook Developer sample apps, however a few days ago both my app and the Facebook sample app stopped working for all users - they now go into an infinite loop after you login: http://myfbse.com/socialmovies/

Here is the link to the sample code I have been using: https://developers.facebook.com/blog/post/2011/03/18/how-to--use-the-graph-api-to-pull-the-movies-friends-like/

I have tested on several computers, different browsers, tried to add and remove the apps from my Facebook account and cleared all cookies etc.

I'm wondering how I can find out what the problem is, a migration issue, a bug or something else? I already ran the app through the Facebook debugging tool and it didn't flag any problems. Is there another way to get more detailed information about what is causing the issue?

Thanks

Answer 1

I fixed the infinite loop by replacing the auth code from the Facebook Developer sample app with the auth code here: https://developers.facebook.com/blog/post/525/

I guess the sample auth code is out of date.
