Looking in the database I see that the data is being added to the wp_postmeta data table, but it doesn’t show up in the Admin interface nor on the frontend.
I don’t know enough about how WP stores/access the DB to do much more at this point though.
I’m seeing the same issue. Any changes made to the Menu Structure (adding a new item, creating a new Menu, reordering the menus, etc) do not save. I click “Save Menu”, the page reloads, and the menu is reverted to its previous settings.
I’ve tried disabling all plugins, that didn’t change anything. I also tried logging out/back in.
Note that the Create Menu functionality also does not work, it reacts the same way.
You ever get this working? Running in to the same problem.
