I’m not sure,how this state was reached. I also tried one new category and added one new product. Product is definitely set to be visible in Catalogue and Search, the category still doesn’t listen it.
I don’t see any code overriding catalog_category_view.xml content. By adding HTML in module-catalog/Block/Category in getProductListHtml before $this->getChildHtml('product_list') I see, that it’s definitely called. I can also see inside module-catalog/Block/Product/ListProduct.php, that the product collection is not empty.
I can see that neither module-catalog/view/frontend/templates/product/list.phtml nor module-catalog/view/frontend/templates/product/listing.phtml is being called, as no static html lands in the output.
Where could I look what prevents the products from being listed?
