Woocommerce 2.3.9 breaks my site.

Latest Enfold installed, no other plugins activated.

While Woocommerce is ACTIVATED I experience the following problems:
Mega Menu: doesn’t expand correctly, incorrect colours
Full width slider layout element: images won’t display at all, no navigation items
Animations: Icons, Icon Lists, thumbnails, images will not animate, NO maps on contact pages, NO maps on Event Calendar (Modern Tribe) pages, image hotspots and hotspots are missing (incidentally, the hotspots are rectangular when woocommerce IS NOT activated and after a fresh install)
Product slider layout element: doesn’t show navigation or products images (front page)

…..amoungst many others

I have since re-installed wordpress 4.2.2 and enfold 3.1.5, re-installed the js files via FTP, and with only Woocommerce 2.3.9 active, and I still have the same problems. I also have the “shop theme” version of enfold installed, just to see if the same problems were experienced on a version dedicated to integrating with woocommerce. I tried to roll back the version of woocommerce to 2.3.4, and that didn’t help either since the same things were occurring.

I have only seen one other forum entry closely related to the above, in that woocommerce breaks their site. But not to the same extent, or even the same symptoms. These only started happening after I updated woocommerce 2.3.8 to 2.3.9.
