Menu
I have a page up and running, (https://blooming-wind-8528.herokuapp.com/) using the following code:
App.rb contains:
require 'rubygems'
require 'sinatra'
require 'open-uri'
require 'json'
#show page
get "/" do
profile = open("https://graph.facebook.com/me?access_token=#full_access_code_here_removed_for_stackoverflow#").read
profile = JSON.parse(profile)
@language = profile['locale'][0..1]
erb :nofan
end
#redirect for facebook
post "/" do
redirect "/"
end
views/nofan.erb contains:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Stestie</title>
<meta property="og:title" content="No Fan"/>
<meta property="og:type" content="website"/>
<meta property="og:url" content="https://blooming-wind-8528.herokuapp.com/"/>
<meta property="og:image" content="https://blooming-wind-8528.herokuapp.com/images/marker_s.png"/>
<meta property="og:site_name" content="NO fan"/>
<meta property="fb:app_id" content="293597294002599" />
</head>
<body>
<p>App running in language: <%= @language %></p>
</body>
</html>
Now, the weird thing: In the browser it loads perfectly. However, on facebook it's not working. I get a blank screen. However, when I invoke an error code (for example: changing the access token to something wrong), I get a full fledged sinatra error page inside the iframe...
Does anybody know what I'm doing wrong?
Thx!

Sinatra tries to avoid a click-jacking attack.
Add this line:
set :protection, :except => :frame_options
or this line:
disable :protection
to you application.
