When a user saves the navigation menu, it may take over a minute to do so. Sometimes the user exits the page, or refreshes or something thinking it's not working. Then we loose the menu.
How to make his not happen? This is a show stopper for us and has cost us hours of time to recreate the menu each time this happens.
I'm looking for all alternatives. A fix for it not to drop menus, a plugin to duplicate the page parent heiracrcy into a navigation menu, a plugin that will duplicate a menu to a new one for a backup.
