I see that the Page Tap app which JFBconnect created doesn't work. Each time I click to it in Facebook page I get this error: http://screencast.com/t/Ig6CxENWFj

The error your showing is because you don't have an SSL certificate installed on your website. To show your website within a Page Tab on Facebook, you need SSL for your site. That's a requirement of Facebook, and not something we can work around in JFBConnect.
