After Migration J3 > J4 click on category link gives 404 error

Hello

I did migrate from J3 to J4.

Now if I click a category link I get 404 error.
No matter if I use main page of shop (storefront) and click category link there or if I click category link in categories module.

I did update all addons and all Joomshopping modules.

How can I solve this?

Thanks.

After some more checkig I figured out:

If a category has subcategories, they are shown (= no 404 error).

If a (sub-)category has products, then the shop throws a 404 error.

Any idea what's wrong?

Call to undefined function formatprice()

I now have selected other Joomshopping template and it works now. Must be an issue in previous template.

Thanks.

There are many changes to be made to the template.

formatprice() -> \JSHelper::formatprice()
