Regarding this, I was just able to log in using JFBConnect for the first time on your site. I can see the Login button and other features of the site. We've tried to make this release even more compatible, even though the javascript error we've mentioned is still there.
What browser are you seeing the missing FB elements in?
Also, we've heard from a few users that the Share module is causing some conflicts. After some research, this is a widely reported issue on the Facebook developer forums (not JFBConnect specific). If you're still seeing missing buttons, can you try disabling the JFBCShare and see if that fixes the issue?
Thanks
