Remove or Edit The WooCommerce Menu Icon
By default if you have the WooCommerce plugin active on the Ocean theme then a little shopping cart will display in the main navigation menu. This icon can be remove and also tweaked via the WordPress customizer.
Browse to: Appearance > Customize > WooCommerce > General
Here you can not only disable the menu cart icon you can also alter it if you want it to link to a custom URL and if you want to display the current cart price.
Important The cart icon in the menu is cached. You must add/remove something from your cart in order to see the difference when altering this setting.
