1) WooCommerce Pages
To use WooCommerce in full volume you have to create main pages which will display products and checkout process. Later you will be able to customise view of such pages: add shortcodes, blocks, change view of a page etc.
So, you have to create service pages for Woocommerce functionality and set them in WooCommerce.
1-1) go in admin left menu Pages -> Add New. Add pages, for example, with such names: Shop, Shopping Cart, Checkout, My Account. Open each of new created pages and add corresponding shortcodes:
-Shop — empty, there is no shortcode.
-Shopping Cart: [woocommerce_cart]
-My Account: [woocommerce_my_account order_count=»15″]
For example, for page Shopping Cart. Don’t forget to press the button Text. And only in Text field write shortcodes.
