This is my application on facebook page.
https://www.facebook.com/SlcChallenge/app_439780382750381
Here my problem is that. Facebook sends signed_request for some user and does’t returns
from some user. So when facebook doesn’t send signed request my page gets error.
my page tab url is https://tippll.com/pagetab.php/
Please help me to find the solution.
Thanks in advance

If on canvas load you receive a
codeinstead of asigned_request, this means that Facebook could not authenticate the user (and retrieve anaccess_token, and has fallen back to sending a code for you to exchange for anaccess_token.Double-check your canvas URL settings in your facebook application. This can sometimes happen if you have URL rewriting non-SSL requests through to SSL domains (or even just url rewrites in general).
