Products not showing up on listing page.

I am using the light green child theme for Shop Theme.
The product shows up on the front page (featured) and I can add it to the cart, but it does not show up when I click on the image I get the product listing page with “This is somewhat embarrassing, isn’t it? It seems we can’t find what you’re looking for. Perhaps searching can help.” The same thing happens with the preloaded times.
