Given URL is not allowed by the Application configuration

Question

I am trying to create facebook sign-in page according to this tutorial. I only changed the two lines

appId      : \'370675846382420\', // App ID
channelUrl          


        

Answer 1

This can also happen when the redirect_uri submitted with the https://www.facebook.com/dialog/oauth request is not present in the list of Valid OAuth redirect URIs under:

• Settings >> Advanced >> Security

After much trial and error, when I added the redirect_uri that I was using (https://www.facebook.com/connect/login_success.html in my case), I suddenly got to the step past this error.
