I don't know if it's because of the recent changes on facebook, or SDK issues.
I'm using the IFrame sample in the sdk and added required permissions in the Master page. The problem is, when I run the sample, it does ask me to login and then goes to the authentication page (e.g. allow posting to your wall, etc.).
The problem is, after the authentication page, it then says "you may close this page now" instead of redirecting me back to the canvas page. I remember a few months back, facebook does have some settings for "canvas call back URL"
or "Post-Authorization URL", but now they seem to remove all these settings... (i cannot find them on fb).
anyone has the same issue?
