错误404无法解决Yii中的请求（已检查其他解决方案但无法正常工作）

我收到了这个错误：

Error 404 Unable to resolve the request "PlanComment/update".

它适用于本地但不适用于服务器 . 我也改变了区分大小写，但仍然不起作用 . 这是我的代码：

PlanCommentController.php

class PlanCommentController extends Controller
{
    /**
     * @var string the default layout for the views. Defaults to '//layouts/column2', meaning
     * using two-column layout. See 'protected/views/layouts/column2.php'.
     */
    public $layout='//layouts/column2'; 

 /**
 * @return array action filters
 */
public function filters()
{
    return array(
        'accessControl', // perform access control for CRUD operations
       //   'postOnly + delete', // we only allow deletion via POST request
    );
}

/**
 * Specifies the access control rules.
 * This method is used by the 'accessControl' filter.
 * @return array access control rules
 */
public function accessRules()
{
    return array(
        array('allow', // allow authenticated user to perform 'create' and 'update' actions
            'actions'=>array('update', 'delete'),
            'users'=>array('@'),
        ),
        array('allow', // allow admin user to perform 'admin' and 'delete' actions
            'actions'=>array('delete'),
            'users'=>array('admin'),
        ),
        array('deny',  // deny all users
            'users'=>array('*'),
        ),
    );
}
 

 ....

                          'buttons' => array(
                                array('items' => array(

                                           'visible'=>(Yii::app()->user->id == $comment->user_id) ||   Yii::app()->user->isPlanAuthor($comment->plan_id)),

                                    array('label' => 'Edit Comment', 'url' => array('PlanComment/update', 'id'=>$comment->id, 'plan_id'=>$comment->plan_id),
                                            'visible'=>(Yii::app()->user->id == $comment->user_id)),
                      )),),)); ?>

                    ),
            ),
