Facebook API error 191

Question

I\'m trying to integrate my project with Facebook. I\'m taking baby steps at first and just trying to login, get a Facebook session, and get some user data. I\'m developing

Answer 1

I was also facing the same problem when I am using the facebook authentication method. But I rectify that issue with following changes in Facebook api (Apps >> My App >> Basic).

1. I removed the url which i have given in ===> App on Facebook (Canvas URLs)
2. I gave site url only in ===> Website with Facebook Login option

Then i gave that AppId and App Secret in my webpage.

So by clicking on login button, It ask for access permissions then it redirect it to give url (Website with Facebook Login ).
