Our facebook page is saying:
Error Summary HTTP Error 405.0 - Method Not Allowed The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.
I've checked Firebug and its sending a POST request to our .html file, which I'm guessing can't receive it? Does anyone know how I get around this problem? I'm hosting on ASP.NET 4.
Thanks!
Change your page tab URL to be a URL which can accept POST requests
This POST request from Facebook includes information which tells you the current page ID, if the user likes the page, etc ( see https://developers.facebook.com/docs/authentication/signed_request/ 's page parameter) which can't be safely passed in a GET request
