I got the same error as you did running it through the online analysis.
Interesting enough, I still have the Chrome extension installed, and this works fine. (Screenshot below).
Why the online version is not working I cannot say for sure. But if you open up your dev tools, you will see that you have a lot of errors (11) in the page. A number of these look like they are related to a number of jQuery plugins loading before jQuery does. So if it were me, I think I would work on getting these errors cleaned up first and then seeing if I could try again.
Good luck
