I'm scratching my head over this one...

I uploaded my site finally to a sandbox on the live server so I can finalize the site.

It's here: https://www.peppermaster.com/peppermaster-shop/

My problem currently is that when I click on any of the products, it doesn't go to my peppermaster.com/peppermaster-shop products but rather to the peppermaster.com categories.

Every other tab goes to /peppermaster-shop



What am I missing?
