[SOLVED] How to remove the category menu bar from header??

How do I remove the category menu bar from the header of Atahualpa

WordPress 2.9.2
with Atahualpa 3.4.9

Ref: www.isatrainingfacility.com

On the page above you can see in black text at the bottom of the header "No categories". We don't use categories on the site, so just want to remove the menu bar, but maintain the background color.
