My Website is appearing as a blank white page in facebook canvas

Question

I changed my app namespace and App Title within developer settings on facebook.

Now my website only appears blank. My application is in sandbox mode but I can make it public if someone needs to reproduce my issue using their facebook account.

These are the canvas urls I'm providing:

canvas url: http://books.botflip.com secure canvas url: https://books.botflip.com

Was it working earlier? disable the sandbox mode so that we may repro the same — Sahil Mittal, Aug 20 '13 at 16:58
yes. was working earlier. sandbox disabled. heres the url: http://apps.facebook.com/botflipbooks — sambehera, Aug 20 '13 at 17:00
does my server need to respond to POST request from facebook? — sambehera, Aug 20 '13 at 17:17
have you disabled the sandbox mode to make sure it is non restricted? — Reno Jones, Aug 20 '13 at 18:57
Can you post the screenshot of the app settings, hiding the secret key — Sahil Mittal, Aug 21 '13 at 06:24

I fixed it!

It was an xframe option issue due to using rails4. Also, rails 4 requires a post route in routes.rb to work well with facebook.

Cannot display my rails 4 app in iframe even if 'X-Frame-Options' is 'ALLOWALL'

thanks for helping everyone!

In your development.rb file:

config.action_dispatch.default_headers = {
  'X-Frame-Options' => 'ALLOWALL'
}
