title: how to turn off facebook signed_request in the page tab?
body: <p>I have a facebook app that gets its contents from nationbuilder.com. When the signed_request is truned off, the app works fine, but when it's turned on I get a 404 error. I think it's because nationbuilder doesn't allow POST requests to their site from an outside source. So it's fine with me as long as I can turn off the signed request in the app settings. My question is, how do I turn off the signed_request for the facebook page tab? The settings for the signed_request only apply to the app, but it doesn't affect the page tab. So, is there any way to make facebook not to send the POST request to nationbuilder? Thanks.</p>
