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