canvas sample aplication does not work

Jul 6, 2010 at 9:58 PM
I get a blank page on the http://apps.facebook.com/fbmlcanvassample/ application as well as on my version of it (just created appid,etc.) Is there a way to debug why nothing comes back? I'm using the 3.0 beta

I still can't get the canvas application to work. , I have debugged it to the point it creates the <fb:redirect url="http://www.facebook.com/login.php?api_key=5f686c6&v=1.0&canvas&return_session=1&session_version=3&cancel_url=http://localhost/myclubs/home.aspx&next=http://localhost/myclubs/home.aspx&req_perms=publish_stream"/> For others that may have this problem, there is a video that they created that shows how to debug by attaching Visual Studio to the w3wp worker process (you have to run on the server where you host the call back URL) If you download the latest patch you get the videos under documentation (maybe they will post on youtube) http://facebooktoolkit.codeplex.com/SourceControl/list/changesets

Your first clue is the localhost in your cancel_url which indicates you are not running your site on an internet-facing server/port. Fix that first.
