wp-e commerce sidebar question

I am working on adding products to one of my sites and noticed that the sidebar isn’t showing up on either the category or product pages. Not quite sure which files I need to revise to add that – or if there is a setting that needs to be switched somewhere. Has anyone else come across this? I’ve searched for hours but can’t figure it out.

You can see the problem here: https://liskabora.com/bar-soap/ and also on any one of the products if you click on them. Since the shopping cart is a widget in the sidebar, I really need to have that part visible.

Any help would be greatly appreciated, thanks! ??
