I need to know on how to reveal the hidden WooCommerce custom fields in products post type. Actually, most of the products on my store are listed with external/affiliate links now some of those products on external sites are discontinued and leading to error 404 pages on their site. I can't remove those links from the admin panel, everytime I try to remove them, they re-appear again and again.
I think, revealing those hidden woocommerce custom fields where data of all Woocommerce post types is saved would manually allow me to delete those external links.
Someone, Please help me out!
