Magento — Ошибка при попытке создать новую страницу таблицы сетки Adminhtml

Я использую Mangento 1.9.0.1.

Я работаю над новым пользовательским расширением, и вот что я сделал до сих пор:

Вот что у меня есть в: /app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sales/Grid.php:

Вот что у меня есть в: /public_html/store/app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sales/Order.php:

<?php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sales_Order extends Mage_Adminhtml_Block_Widget_Grid_Container
{
public function __construct()
{
$this->_blockGroup = 'smsnotification';
$this->_controller = 'adminhtml_sales_order';
$this->_headerText = Mage::helper('smsnotification')->__('Orders - Inchoo');

parent::__construct();
$this->_removeButton('add');
}
}

Когда я захожу в админку и нажимаю на SMS on Order Statuses я получаю следующее сообщение об ошибке:

a:5:{i:0;s:51:"Controller file was loaded but class does not exist";i:1;s:1078:"#0 /home/superweb/public_html/store/app/code/core/Mage/Core/Controller/Varien/Router/Standard.php(327): Mage::exception('Mage_Core', 'Controller file...')

Я сделал все по этому руководству: http://inchoo.net/magento/how-to-create-a-custom-grid-from-scratch/

Можете ли вы помочь мне решить эту проблему и помочь понять, где моя ошибка?
