Hide bar under menu

Please, can somebody tell me how to hide that red bar under menu?

I don´t have any submenu

Thanks a lot

I don´t know if this is the best solution, but I solve it changing heigh in this line of template.css

#gk-subnav { background: #6e9a1e; font-size:11px; height:30px; margin:0 2px; padding:0 0 0 18px; }

Thanks

Hi

I think the best option is this code:

#gk-nav ul.level0 > li > div.childcontent {
display: none !important;
}

it will remove submenu, but please show me Your site first.
