Starting with our ContentController, we first want to remove the actionAdmin(), actionSave(), and actionDelete() methods from the ContentController.php file at protected/controllers/.

Next, we should remove the access control properties for the actions we just deleted from our ContentController. The restored accessRules() method should look as follows:

public function accessRules()
{
   return array(
      array('allow',
         'actions' => array('index', 'view', 'search'),
         'users' => array('*')
      ),
      array('deny',  // deny all users
         ...
