[color="#FF0000"]‘controllerMap’ => [

    	'article' => [

        	'class' => 'backend\controllers\PostController',

        	'enableCsrfValidation' => false,



then I went to terminal for Ubuntu and then writed command of [color="#FF0000"]symlink of ln -s post/ article[/color]

,But when I used article controller instead of post controller,the error is occurred.
