Hello, help me please to change the Menu hover color,
from administration panel I can change the color for everything.

I've found how to change the color only for menu

#overlay-menu-content .sub-menu.gk-active a:hover { color: #fdff21; }

#overlay-menu-content a:hover { color: #fdff21; }

Hi,

I'm not sure, Is the entire problem solved or you need further help?
