When I set one product to „hidden“, so it is not visible in the store anymore, the pagination does not work correctly anymore. I have set the „products per page“ to 12, which is working fine. When I hide one product from the store, there are only 10 products per page in the store.
We are going live today, so I can not let you do these changes to our site. So you are not able to reproduce this issue? For your information: The product, that I have set to „hidden“ is a variable product with two variations..
