Can't access single product pages on mobile responsive layout

I’m about to go live with my site, and I’ve noticed that on the mobile part of my theme’s responsive layout you can’t access single product pages.

For example, starting on this page here: , you can work your way into the categories and subcategories (such as Operatory and then Impression Trays), but you’re unable to click on a single product. An example of a single product would be these BoTrays, which is up and working, but can’t be accessed with a click from the mobile layout.

Any ideas on how I can fix this? I’m using the CoPro theme and WooCommerce. Support for my theme had no resolution…
