In this post, I’d love to share with you guys a solution to fix the Facebook login error which could happen for social login function with Facebook. The exact error message is:

The error message popup dialog looks like this:

To solve this Facebook login error, sign in your Facebook Developers home page (https://developers.facebook.com), click menu My Apps at top right corner of the page. Select your Facebook App that has the problem, and click Settings under Facebook Login, as shown below:

The under the Client OAuth Settings section, type the following redirect URL into the text field Valid OAuth Redirect URIs:

https://localhost/login/oauth2/code/facebook

This is for localhost (use http:// if you don’t have SSL setup for localhost). You may need to use your own domain name:

https://yourdomain/login/oauth2/code/facebook

It should look like below:

Click Save Changes. And test social login with Facebook again. It should be working now. Enjoy!
