I believe this occurs when you have jQuery version 1.9.* or above. (In your case, you have 2.1.4).
The browser has trouble “sniffing” the browser for information.
For a fix, try and add this reference after loading all your jQuery files (core_htmlhead possibly unless you’ve referenced them in layout or elsewhere).
The downgrade kept the same error. I tried the migrate. Up to v1.4 and it messed up the schedule search when you searched for a schedule. It put the page inside a page. Weird, see what I am talking about.
Yeah, that is weird. I think it’s just echoing another template inside the original page, weird how it’s a full page though. Have you modified your schedule search at all. (module or template)
Can you try changing your jQuery version to 1.8.3 and see if that works (again, might break things but its below 1.9.0)
Do you need these script files for the skin to work? What if you remove them (referenced under your footer).
