Facebook Connect feature is not working

[Sieg]

Facebook Log In button is shown near OXID login button, it gives facebook login form, but have no reaction on facebook response. Logging in as facebook user doesn't create any user in the OXID database and not setting any facebook id for existing users.

On the Facebook developer page you get the code and i guess its only necessary to update it!?

Control your settings in facebook developper. Maybe something have changed with the new GDPR.
I have just solved a similar problem with my facebook account.
