I had installed Divi theme on my website. I created many layout, for pages, posts an woocommerce products. All these layouts worked good.
Now I changed the theme. I installed Atra theme. All the layout work good but not the layout of woocommerce product. I set a layout for all woocommerce product but when I open i product I don't see what I aspect (the layout created) but the original woocommerce product template.
