Wordpress - Remove Woocommerce product link

A better & safer way to do this is by removing the open & close link actions. This will prevent side effects such as the add to cart button disappearing.

remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_product_link_close', 5 );

You can add this code to your functions.php
