Active link doesn't work

Hi, is anyone having the same problem? The active link in the menu is showing #fff….hover works showing color: #8fc73e, but not the current_page_item…

Does anyone have a fix for it? Much obliged. Thanks!

#topmenu ul ul a:hover {
	color: #8fc73e;
}
#topmenu ul li:hover > a,
#topmenu ul ul :hover > a {
	color: #8fc73e;
}
#topmenu ul li.current_page_item a {
	color: #8fc73e;
}
