remove total and subtotal checkout box

Hi there,

This would be a question for WooCommerce support.

I found this that might help:
https://stackoverflow.com/questions/53277895/remove-subtotal-line-from-cart-and-checkout-pages-in-woocommerce

So try:

add_filter( 'woocommerce_get_order_item_totals', 'remove_subtotal_from_orders_total_lines', 100, 1 );
function remove_subtotal_from_orders_total_lines( $totals ) {
    unset($totals['cart_subtotal']  );
    unset($totals['order_total']  );
    return $totals;
}

Adding PHP: https://docs.generatepress.com/article/adding-php/o

good read I have inserted the php code with the code snippets plugin, but I have not seen any change in the cart or checkout, thanks

Hmm unfortunately you might have to check with WooCommerce support.

If you are happy with CSS then try this:

.cart_totals h2, .woocommerce-cart .cart-collaterals .cart_totals table {
    display: none;
}
