Catalog mode settings
The plugin free version allows to hide “Add to cart” button in product detail page and in any other WooCommerce archive page by enabling related fields in YIT Plugins -> Catalog Mode.
This way, “Add to cart” button will be hidden to all users, registered or not. By enabling “Admin View” field, “Add to cart” button will be hidden to site administrator too.
By disabling the shop, WooCommerce “Cart” and “Checkout” pages are hidden and no one can have access. Furthermore, “Add to cart” button is removed where expected in the pages of the site.
