The FoodAssets is right, modules cannot be taken for everything. I have a module schema-markup-tool-with-rich-snippets-seo-module but that doesn't solve things. I have no errors, https://beautyandpower.eu/ neither for products nor for categories, but the warnings are enough. I remove from product list tpl and from product tpl all itemscope, itemprop and the warnings disappeared, but it's not a solution and I returned the original files.
