You do indeed have a jQuery problem. I inspected the page source HTML and see quite a few files with the 1.11.4 version query strong on the end (1.11.4 was the old version of jQuery used by WordPress; it now uses 1.12.4), so I am wondering whether any of these files has code in it that is not compatible with jQuery 1.12.4
It could also be any javascript associated with other plugins. In the first instance, disable as many plugins as you can without stopping S&F from working (you should be able to deactivate most, if not all, plugins). Then check again. However, these are the suspect 1.11.4 file calls in the source HTML:

These look like they might all be theme files?
