Ah I see. So or so you need to use one of the packages added, so that WooCommerce looks for the template overwrites in the correct directories. So install one of them and you should be able to use regular .php files as well (as far as I remember).
Hi, I have been using the https://github.com/ptrckvzn/sage-woocommerce repo for Sage 10 and I have been experiencing an issue where overriding the content-product.php file, causes duplicate products to be shown. Basically it loads both the original template and the overridden template. Does your version solve this issue?
This is the same solution/repo I am currently using. Like I said, I only broke it out into a repo and made it simple to install. I haven’t had any duplicates but I am not touching content-product.php. Below is an image of the WooComm template files I am currently successfully overriding.
