One of the great things about Yootheme's templates is Active Item Dectection. With many of their templates the Active Item is highlighted in different colors, which can be set in the template section. For it to work, your params.ini file should be writable (755) and the main menu items should be ordered consecutively in the menu manager.
Recently I saw that the Active Item Dectection on one of my sites was not working. I used the Waybeyond template on that site, which was also installed on another site and still working perfectly there. I checked the parameters, installed the latest update for Waybeyond, but still no joy.
Then I began the laborious work of browsing through the Yootheme forums on this template. It turned out that Active Item Detection doesn't work when the cache is set to on in the System settings of the Global Configuration of Joomla! Usually I turn that off when installing Joomla!, but I must have missed it somehow. When I turned that off, Active Item Detection began working again. One can also leave the setting to on, and turn it off in the specific menu module (Module Manager | Advanced Parameters).
