我创建了一个新的表格费率部分，每当我尝试保存它（在网站级别）时，它似乎都会出错。我一直在关注本教程：http ://www.excellencemagentoblog.com/magento-create-custom-shipping-method
并编辑了这些文件：
Shipping/etc/system.xml
Shipping/etc/config.xml
Shipping/model/carrier/NEWCARRIER.php
Adminhtml/Model/System/Config/Source/Shipping/NEWCARRIER.php
并且还插入了一个新表
NEWCARRIER
website_id | dest_country_id | dest_region_id | dest_zip | condition_name | condition_value | price | cost
似乎仅在我尝试激活自定义表格费率时才会发生。

错误：
An error occurred while saving this configuration: Warning: include(Mage/Shipping/Model/Mysql4/Carrier/NEWCARRIER.php) [function.include]: failed to open stream: No such file or directory in /shop/lib/Varien/Autoload.php on line 93 **-- I've Fixed this**
新错误：
