Within Dashboard > Menus The page and category menu has disappeared from view.

Hi,

The page and category menus have disappeared from view. The pages are listed on the left, but no menus to select! Both menus still display just fine on the website.. http://onthewaytokrishna.com but they are not longer available to add/delete pages from. Spooky....

If any one can lend a hand I'd be very appreciative.
