@ukguy – While we look at our options here, you can setup a redirect instead here in your MemberPress Options: http://cspf.co/fW5D/Image%202016-03-24%20at%204.06.59%20PM.png
That will redirect the user away from the page they should not have access to and instead take them to your unauthorized page.
I haven’t had a chance to use AFC yet, so I’m honestly not sure how it works to output its content at this point (shortcodes, theme hacks, appending to the_content)?
