Hi Team, we have a portal and we have implemented facebook like button in our portal. But when we click on like button it's throwing below error

"Refused to display 'https://www.facebook.com/' in a frame because it set 'X-Frame-Options' to 'deny'."

FYI we are using below source script to implement like button in our portal //connect.facebook.net/en_US/all.js#xfbml=1

and the implemented fb tag looks like in our code

Could you please guide me how to resolve this error and make like button works properly
