I was trying to do some sample facebook canvas application,
I have created the app in Facebook developer and created new platform in side facebook canvas.
I have give Canvas secure Url as https://www.google.co.in/, https://www.audiotube.com/, https://bitbucket.org
SO I opened the app page which is not loading the data
But If I use other https websites means It will load for ex. https://eatwater.co.uk
