Filter doesn't work

Hi!
I’m trying to use the plugin on http://acelere.vc/homologacao
The thing is that when I check the checkboxes de filter doesn’t reload the page and doesn’t return the products. This happens on the shop page.
I’ve check everything at all, and also all the other topics in this forum.

Note that on the single pages and posts the widget doesn’t even loads.

Hope someone can help me!
