Products not showing up in collection page

No, it didn’t answer my problem.

I do not know what happened, but the products wouldn’t show up with the link to my collection but it did give me a filter option. When I changed the filter option to all products, things came up. Now for some reason it is all gone and the links are not working. When I click on the collection button, it just takes me to the top of my home page again. It wasn’t and isn’t linked to the homepage. Nothing changed that i know of that should affect this.

When I use the side menu, it goes to a product page that has no products on it, and even though I’ve enabled the filter, there isn’t a filter.

The only think I know is that i deleted Debut, because I’m using the Simple Theme. Is that why I lost everything.
