Ok, let me see if I have the concept down. I have been reading and re-reading this link:
www.sourcecoast.com/jfbconnect/docs/facebook-page-canvas-setup
I already have an article ID that says something to the effect: Like us on Facebook and get a 25% discount. I see that article ID in JFBConnect under Page Tab/Canvas and then in the Application as Page Tab, as the Reveal Page Article Id.
Within the FB App, just for grins, I changed the Page Tab Name and saved those settings. I see that FB App as a Page, but when I click on it, I get "The Connection is Untrusted". I'm guessing I have missed something at the host with the UCC/SSL, but am not quite sure.
Do I create another Joomla article, the one that provides the discount code, and use it as the Page Tab URL?
Feels like I'm pretty close, but not quite there.
Thank you Alex!
