FBConnect iOS sdk: unknown_error

Question

I'm trying to develop Facebook integration with my app.

The problem starts when the Facebook.app is installed on the device: When a user tries to register and the app isn't installed, she is redirected to Safari which shows the approval page and everything works fine. When a user tries to register and the app is installed, she is redirected to the app, the app seems to be processing, but no approval page appears and then it returns to my app with this URL: fb***************://authorize#error=unknown%5Ferror

The Facebook.app version is 4.0.2

Any help on this subject on how to continue debugging this issue will be much appreciated.

Thanks

Ran tip really helped. In my case deleting the bundle ID from the app configuration at Facebook solved this issue.

For those who missed, Ran directed me to this post: iOS Facebook connect not working when user has FB's app installed?
