Yii Db Profiler Not Working - 'enableprofiling'=>True

i have enabled profiling to be displayed in yii as below shown.

'enableProfiling'=>true

but still i am not getting anything displayed under the pages of website and its empty.

before it worked and recently i switched off by

'enableProfiling'=>false

why doesn’t it work ? i must be missing something.

Make sure you’ve enabled CWebLogRoute:




			'routes'=>array(

				array(

					'class'=>'CFileLogRoute',

					'levels'=>'error, warning',

				),

				array(

					'class'=>'CWebLogRoute',

				),

			),
