I am creating the menus using wordpress menus, NOT custom links. When I change a menu item and save it, each menu item is listed twice, ie. Home Home About Us About Us etc. The menus work fine on the old version of the site using WordPress’s Twenty Ten (a child theme of that, actually), but do this crazy thing on the new site I’m creating with Weaver Xtreme. There are the same number of menu items on both versions of the site. Since the other site works fine, I don’t think it is a WordPress problem.
I’m not even sure where “WordPress Custom Menus” is. I see custom links, but no such thing as Custom Menus.
