I am trying to get an FB application to display it on the application page on facebook, but the iFrame just doesn't work. The application works fine on localhost and appspot, but nothing happens when loading inside facebook.
If I look at the source of the iframe, nothing appears, but if I refresh this page, will all the code display normally?
I also tried the sandbox, and I have two separate application settings for localhost and appspot. Both are doing the same.
This is my main application code.

and my JS download on the main page
