I am using helix3 template, the menu item "home" is not taking "active class" when I'm on the home page or when I click on it although the other menu items are working fine, i want it to take the active class style and change its color when I am on the home page, it was working before!!
Try clearing your joomla cache. I also run into that problem with some templates if I have system cache turned on. So if that is on, I would try turning that off as well.
Go to "Helix menu Options" Tab and add the class there in "Custom CSS Class" It gives the class to "li" so it is better than the native Joomla class.
after the color value and it shall take precedence over other value that is stopping it.
