Yii模块仅适用于本地主机，但不适用于网站

我有一个网站，我使用Yii引导框架开发它。然后我只想创建一个评论模块，我从Yii下载了这个模块(链接如下):

注释模块链接

然后我在我的本地主机上测试了它，它工作了。然而，评论模块不工作在我的网站。

下面是main的代码:

<?php
require_once( dirname(__FILE__) . '/../components/Helper.php');
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');
Yii::setPathOfAlias('bootstrap', dirname(__FILE__).'/../extensions/bootstrap');
Yii::setPathOfAlias('CoverUploadDir', dirname(__FILE__).'/../../uploads/covers');
Yii::setPathOfAlias('ContentsUploadDir', dirname(__FILE__).'/../../uploads/contents');
error_reporting(E_ALL ^ E_NOTICE);
// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.

我已经遵循了所有的指导方针，但我真的不知道是什么问题。当我调用 下面的别名时

 $this->widget('comments.widgets.ECommentsListWidget', array(     'model' => $model, ));

它不会显示任何错误，但是我的页面会变成白色，所有的主题都不见了。它只显示内容，不显示注释模块。我认为我的url管理器有问题。我已经尝试实现以下代码，但仍然没有成功

'<modules:'w+>/<controller:'w+>/<action:['w-]+>' => '<modules>/<controller>/<action>',
'<modules:'w+>/<controller:'w+>'                 =>        '<modules>/<controller>',
'<modules:'w+>'                                  => '<modules>',

syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM

$this->_ownerModel = $ownerModel::model()->findByPk($key);

$model = call_user_func(array($ownerModel, 'model'));
$this->_ownerModel =  $model->findByPk($key);
