How to remove the sub title of the product tabs

Hi Hana,

Here’s a PHP snippet you may try adding:

add_filter('woocommerce_product_additional_information_heading', 'remove_product_additional_information_heading');
 
function remove_product_additional_information_heading() {
    echo '';
}

Adding PHP reference: https://docs.generatepress.com/article/adding-php/#code-snippets

Kindly let us know how it goes.

Thats great!
Thank you

You’re welcome Hana!
