The menu_class parameter of wp_nav_menu() controls the class added to the

wrapper element, rather than the individual
• 's. To add classes to the menu items, you want to use the nav_menu_css_class filter.

  Here's how it works (add this to your theme's functions.php file):

  add_filter ( 'nav_menu_css_class', 'so_37823371_menu_item_class', 10, 4 );
  
  function so_37823371_menu_item_class ( $classes, $item, $args, $depth ){
    $classes[] = 'menu-li';
    return $classes;
  }
  

  This will add the menu-li class to every menu item.

  You can also do this conditionally based on the $item, $args etc. passed to this filter if you like.
