I have a site with WooCommerce, Storefront and a child theme. When I upgraded the site to WordPress 5.5.1 a page menu item called “Product Categories” says it is invalid. I am uncertain what happened to this page. It is not found when searching.
The site uses a plugin called Max Mega Menu and there is an extensive product menu that was build under “Product Categories.” It there any way via MySql or other to reassign a menu item to another page so that it is no longer “invalid” without having to rebuild the entire menu?
