        'preload' => array('log'),

        'log' => array(

            'class' => 'CLogRouter',

            'routes' => array(

                array(

                    'class' => 'CFileLogRoute',

                    'levels' => 'error, warning',

                ),

                array(

                    'class' => 'CProfileLogRoute',

                    'report' => 'summary',

                    'levels' => 'profile',

Is YII_DEBUG enabled? CWebLogRoute will work with or without it, but CProfileLogRoute only works with YII_DEBUG = true
