Below SW 5.4 or so you have to add your controller manually,

For example, add the following lines of code in the subscriber

‚Enlight_Controller_Dispatcher_ControllerPath_Frontend_ControllerName‘ => ‚functionName‘,

public function functionName()
{
return DIR . ‚/…/Controllers/Frontend/ControllerName.php‘;
}
