My site is using the Hemmingway theme, I have a menu in the header.
This is the menu whose structure results from assigning a "parent" on a page's edit form.
One of my pages is less important and should not appear in the menu. (It is accessible through links from the body of other pages.)
I went to Appearance->Menus (/wp-admin/nav-menus.php) and removed this page under the Menu Structure list (there is only one menu there, "Menu 1". Yet this page still appears in the header menu.
How do I remove it from the header menu?
