You can disable the slide out cart and link the cart icon in the navigation bar directly to the cart page if you wish. This is the slide out cart:
To disable this, go to:
Appearance > Customize > Layout > WooCommerce – and set Enable sidebar cart drawer to off. If you don’t see this option just update the theme to the latest version.
You also need to go to
WooCommerce > Settings and click on the Products tab. The Enable AJAX add to cart option should be unticked.
