We upgraded our Drupal to 7.54 and several modules to their current version.
When I go to admin/structure/menu, I see links for Manage Fields and Manage Display (this is not where they are on the production server) but when I click on them, it says You are not authorized to access this page. And I am logged in as the root admin.
I am also missing the Manage Fields and Manage Display tabs in admin/structure/menu/manage/main-menu. Is this found elsewhere now?
