Magento的1.6.x分支重新构造了Mage_Usa_Model_Shipping_Carrier_Abstract的工作方式，其中包括添加了所有子类都必须实现的抽象方法.

The 1.6.x branch of Magento re-factored how the Mage_Usa_Model_Shipping_Carrier_Abstract works, which included adding an abstract method that all child classes must implement.

您的系统上有一个名为Zenprint_Ordership的模块，其中包括货运公司类.它可能是此扩展名的一部分.

You have a module named Zenprint_Ordership on your system, which includes a shipping carrier class. It's probably a part of this extension.

此扩展程序尚未更新，无法与Magento 1.6+一起使用.要使您的商店再次正常工作，您应该通过重命名/删除文件

This extension has not been updated to work with Magento 1.6+. To get your store working again you should disable this extension by renaming/removing the file

#rename so it doesn't have a xml extension to disable
app/etc/modules/Zenprint_Ordership.xml

app/etc/modules/Zenprint_Ordership.xml.disable

这将删除您使用Zenprint_Ordership的所有自定义功能，但应使系统恢复工作状态.

This will remove whatever custom functionality you were using Zenprint_Ordership for, but should return your system to working order.

长期而言，您要么需要

1. 重新编码Zenprint_Ordership模块以与您的系统一起使用，因为自Magento 1.2以来，开发人员似乎尚未对其进行更新.

1. Re-code the Zenprint_Ordership module to work with your system, as it looks like the developer hasn't update it since Magento 1.2.

找到使用Zenprint_Ordership的功能的替代方案.

Find an alternative for whatever functionality you were using Zenprint_Ordership for.

此外，即使在禁用扩展程序之后，在查看使用此送货方式的旧订单时，您也可能会遇到问题.如果您对此感到满意，则在类上定义一个空白的_doShipmentRequest方法可能会帮助您解决此问题，但是我不确定是否会推荐给非程序员.

Also, even after disabling the extension you may run into problems when viewing old orders that used this shipping method. If you're feeling up for it defining a blank _doShipmentRequest method on the class may help you work around this, but I'm not sure I'd recommend it to a non-programmer.
