Our app was working fine but, without any change on our side, when we tried to enter our Facebook app outside the canvas (directly on http://example.herokuapp.com), and after providing our FB user and password, we are stuck in an infinite loop where the "state" parameter on the URL is constantly changing:

https://example.herokuapp.com/?state=05b40a2e4d2c1f7b4c13a026a069acc3&code=AQCql520w_5dJjHnJlojMvzSCukAMrRsjqCipdkDP3N4h4zUQH72Q79oH2EMd_tQDv-fwKTJr2LG-azBUt37bUX06r3t9QHBwb27XBQyxmgdGdR_A1flZBY_oP-L0UEhjSu1FE8v2blILC8EuEWLNikgtkmaWWwy9e93KQX00wiVj422pzHuzn-m9_jZEUiKsf3dQIwCE3V7UBHMZCD9gS0#_=_

Inside the FB canvas it is working fine. And we have a twin app (test environment) that is working fine inside and outside the canvas (same code and configuration).

Any ideas?

Thanks

Can you post your code? Are you using javascript sdk to handle the user status? – Fabio Antunes Apr 16 at 11:40

did you try to delete your cookie and try again ? also note that heroku app may switch storage/server at the backend, any state data stored on disk may be destroyed, so make sure you use a "shared session". – w00d Apr 18 at 20:37

You did post that question twice, and added a bounty to both of them.. That is weird :P

Facebook app on infinite loop trying to log in out of canvas

As I already answered, someone had the same problem and made a blog post on it :

Might be a configuration problem.

Try updating your sdk too.

Clear cache and cookies.
