targets the submenus, which is also specifically targetted by ".genesis-nav-menu li ul"

change selector accordingly, and also use .sub-menu instead of ul */

I have used this menu and added .sf-sub-indicator to my navigation. The strange part is I can view the indicator just in my pc. even its localhost or online server. But no other computer can view it. When I check in other pcs the indicator is not generating but the same online link when I view it in my pc I can see the indicator and its generating. Please help me what is the issue.
