WordPress Menus "Manage Locations" tab is missing

Question

I have a fresh install of WordPress 4.0.1 running Twenty Fourteen theme with no plugins activated.

When I go to Appearance > Menus, I only see one tab "Edit Menus". "Manage Locations" tab that I used to have in earlier versions is missing.

When I create a new menu, it's not visible. However, if I try to create a new menu with the same name, I get an error message, "The menu name TESTMENU conflicts with another menu name. Please try another."

It turns out some themes does not have menu locations and you need to add theme manually through your theme's functions.php. Anyhow, here's what I did:

add_theme_support( 'menus' ); // <-- if you already see `menus` from your settings menu, you can ignore this line.

function register_menus() {

  register_nav_menus(
    array(
      'primary-menu' => _( 'Primary Menu' ) // add locations here.
      'your-preferred-menu-location-id' => _( 'Title of your menu location' )
    )
  );
}

add_action( 'init', 'register_menus' ); // <-- of course without this, the function above will not execute.

If the code above does not work for you, try enable/disable plugins that might be causing the issue.

Hope this helps.
