App Not Setup: The developers of this app have not set up this app properly for facebook login even app was released

Question

I developed a game by Unity 4.3 with Facebook Official SDK Plugins for Unity, and the game was released a few weeks ago, and work fine. However, I got a few report that players cannot login to facebook and got this error message. I tried to logout from facebook and login again, but I got this error.

I am very sure that my facebook app is NOT in sandbox mode and the option is YES in status and review, but I still get this error. any idea for me ?

Thanks you !

You have to make sure for below points to be correct:

1. Is your app submitted in developers.facebook.com
2. Have you filled correct details of the app in developers.facebook.com.
3. Is the app made Live for all users in developers.facebook.com.
