I just went to that page but was unable to see that error message. The line of code referenced relies on our jfbconnect.js file to be loaded onto the page properly, and that looks to be happening on your site.
Can you check again if you're still seeing that error? If so, we'll gladly help investigate further, but I'm unsure what's happening.
No problem. I'm glad to hear it's working and that there's nothing we needed to do Sometimes after upgrades, there can be caching issues either in your browser or within Joomla. They usually clear themselves up after a little time.
