Elementor does not include woocommerce_before_main_content action in their wc-product-archive widget. WC Vendors use this hook on the Product archive pages to display the vendor store headers on both the vendor store and the vendor single product page.
If you are creating a product archive and product single template override in Elementor then the store headers will no longer display. The following code snippet will add the required WooCommerce hook back to the widget so that the vendor store headers will output correctly.
Please Note
As always, this code snippet will be added to your theme’s functions.php.
