I am using the Divi theme (not a woocomerce) I installed the normal woocomerce plugin and configured it in the theme, Divi does not have that option to enable catalog so I installed the plugin: YITH WooCommerce Catalog Mode, it is the plugin that deleted the add to cart buttons on the products.
It happened to me the same as the comment: https://www.ads-software.com/support/topic/serious-problem-when-deactivating-the-plugin/ (but since it has no answer I opened another topic)
Is there any way to fix it?
