title: Cannot see "Enhanced Auth Dialog" setting in my app settings
body: <p>I can't seem to find the option "Enhanced Auth Dialog" like the <a href="http://developers.facebook.com/docs/opengraph/authentication/" rel="nofollow noreferrer">docs suggest</a>, it's simply not listed under "Advanced" do I need to configure anything else in my app settings to get this option available?</p>
