Remove recent Customizr update

To some degree, my 3-bar menu problem illustrated above seems to be linked to the new Navigation options in 3.1.5. With the main menu set to expand on hover, my 3-bar menu loses its nesting.

Changing the main menu setting to expand on click, the 3-bar menu does deliver a crude nested menu when clicked – but the nesting doesn’t work: the sub-menus don’t appear.

This is with 3.1.5, WP 3.8, no custom CSS and all plugins de-activated.
