Blank Facebook Canvas With Rails
Facebook Page Tab App Is Blank?
Facebook page and canvas apps with Rails 4, can lead to a blank white page. In Rails 4, the X-Frame-Options are sets by default, and you should override them, to allow iframes in Rails.
class FacebookClubsController < ApplicationController
layout "facebook_canvas"
after_filter :allow_iframe
def index
end
private
def allow_iframe
response.headers["X-Frame-Options"] = "GOFORIT"
end

Why set an invalid value for it when you can just remove it altogether?
def allow_iframe
response.headers.except! 'X-Frame-Options'
