Hi sailwinthu, I’ve tried to implement a facebook login with both JS + PHP server side by using an AJAX Post. Although, I’m getting the same error. How did you solve it?

Cheers :)

Hi, Thanks for the answers. It’s getting resolved by a friend who help me to login to server and fixed it. facebook login button was not working because it’s require some kind of plugin.

I appreciate all your respond.
