The site is: https://www.jt5designs.com. The menu link for "Store" is set to go to: https://www.jt5designs.com/products/?cat=Smooth-Shot -- which is the main category of the store. When I first click on it, the correct page opens up, then if I try it again I get a "Not Found" page.

This site was set to launch today and I can't understand why this is happening.

Can anyone help?

Got this working - sorry!
