I’m trying to run the example.php file that comes with the facebook sdk. I do have a hosting server that runs php, and also changed the ID’s to the corresponding one on my app. Here is the message i’m getting:

This webpage is not available
The webpage at https://filipeximenes.com/facebook/ might be temporarily down or it may have moved permanently to a new web address.
Error 501 (net::ERR_INSECURE_RESPONSE): Unknown error.

i’m pointing the canvas to this adress: http://filipeximenes.com/facebook/

Thanks.

    Based on your description, I think that this is your problem:

    Do you have a valid security certificate on the hosting server? I ran into that problem recently when deploying an FB app. Since October, you have to have a valid cert even in sandbox mode for the FB app to run properly. If you don’t have one it causes weird problems.

    Just a thought that I hope helps.

    One other thing to do from a debugging perspective is to take a look at the actual app running on your hosting server without viewing it via FB. If you get the same error message there, you know that it has nothing to do with the FB SDK.

    Thanks!
