Question

My Rails app runs in a FB canvas. The problem:

If the user isn’t logged in to Facebook, there is a redirect to the Facebook login / auth page. However, that doesn’t work in the canvas, because the facebook auth page doesn’t allow itself to be loaded into an iframe. This is the console error:

Refused to display document because display forbidden by X-Frame-Options.

So users can’t log in to FB to auth the app. It works fine when not running in the canvas.

How can I fix this?

Solved

Added :target => "_top" to the link and it works fine now.
