 Would get the warnings below, and menu wouldn't show. Changing the code
 shown here (I left the original in, just commented out. fixed the issue.

 ------nav-menu-template.php------
         // Calculate the depth of each menu item with children.
         foreach ( $menu_items_with_children as $menu_item_key =>
 &$menu_item_depth ) {
                 //$menu_item_parent = $menu_items_tree[ $menu_item_key ];
                 $menu_item_parent = isset($menu_items_tree[ $menu_item_key
 ]) ? $menu_items_tree[ $menu_item_key ] : null ;
                 while ( $menu_item_parent ) {
                         $menu_item_depth  = $menu_item_depth + 1;
                         //$menu_item_parent = $menu_items_tree[
 $menu_item_parent ];
                         $menu_item_parent = isset($menu_items_tree[
 $menu_item_parent ]) ? $menu_items_tree[ $menu_item_parent ] : null ;
                 }
         }
