Facebook: auth flow is not allowed

Question:

I followed Facebook online dev. docs. but web api responds me: "Platform auth flow is not allowed: The application has disabled this authentication flow."

What should I turn on or off in order to make valid api calls? Thanks!

Answer1:

If you get the <em>"Platform auth flow is not allowed: The application has disabled this authentication flow."</em> error, then you have probably not enabled the OAuth client login flow for your app. To enable this, visit your app's settings page, click on Advanced, scroll down to the Client OAuth login box and make sure that it is ON. Then scroll to the bottom of the page and save the changes.

If this did not work, double-check whether you've inserted the correct App ID in your app.

You need to enable Client OAuth Login in your Facebook App Settings. It comes under the product Section. If there is no product. First you have to add the product Facebook Login and then you can enable the login..
