Is anybody using Facebook API by Matthew Combatti.

Hi to all,
I decided to experiment with Facebook API, just in case… But it seems that the facebook developer page has somewhat change.
The instructions said that "Jump down to the “Client OAuth Settings” groupbox and toggle “Client OAuth Login”, “Web OAuth Login”, and “Embedded Browser OAuth Login” switches, all to “YES”
but cant find such settings, so can’t use it by providing just App_ID…
It seems that there are some changes to facebook developers app?
Anything that uses FAcebook API to give a hand?
