Facebook connect error

Hi, i'm using version 7.0.9 and i have some problem with my facebook connect. Is facebook connect not working now? I trying to make the setting for the facebook connect but the i cant get it to work. I get some errors all the time.

API Error Code: 100
API Error Description: Invalid parameter
Error Message: Please migrate to OAuth2 and use new /dialog/oauth endpoint. return_session is no longer available.

does anyone know what the problem is or if it does not work now?

Facebook updated their API, and Facebook connect module in Dolphin 7.0.x becomes not compatible with their API now.

You need to upgrade to 7.1.x, or use 3rd-party Facebook connect modules.
