We received the following message from Facebook on one of our Tab pages for a business. The page is just a simple graphic using an iframe canvas and is hosted on an https://
URL, so I really don't know what else I'm supposed to do.
Surely, I'm not the only one to encounter this problem! Can you tell me what action I need to take?
Reminder: Upgrade Your App to OAuth 2.0 and HTTPS by October 1st. In May
we announced that all apps on Facebook need to support OAuth 2.0 and HTTPS
to make the platform more secure.
All apps, including page tab apps, must migrate to OAuth 2.0 for
(FeatureLoader.js) and old iOS SDK (facebook-iphone-sdk) will no longer
work. In addition, iframe Canvas and Page Tab apps must support HTTPS and
provide a secure canvas or secure page tab URL.
