Unsafe JavaScript attempt to access frame with URL: Domains, protocols and ports must match.

Question

I'm trying to set the height of the app by calling:

FB.init({ appId: fbAppId,
            status: true,
            cookie: true,
            xfbml: true,
            oauth: true,
            channelURL: webUrl + '/channel.html'
        });
FB.Canvas.setAutoResize();

And it doesn't work if it's on HTTP but works on HTTPS.

Sample URL: http://www.facebook.com/ListerineAU/app_300955373319633 - doesn't work https://www.facebook.com/ListerineAU/app_300955373319633 - works

Error message:

Unsafe JavaScript attempt to access frame with URL http://www.facebook.com/ListerineAU/app_300955373319633 from frame with URL https://s-static.ak.facebook.com/connect/xd_arbiter.php?version=5#channel=f35120b198&origin=http%3A%2F%2Fjwteeth.aptira.com&channel_path=%2F%3Ffb_xd_fragment%23xd_sig%3Df2eb2cde4%26&transport=postmessage. Domains, protocols and ports must match.

It seems to be error on FB ends, has anyone else experiencing this?
