Magento:无法检索实体配置：销售/销售订单

Magento在试图查看管理后端的Sales->Orders页面时显示以下错误报告

我已尝试重新生成缓存并启用/禁用编译器，但均未成功清除错误

其他需要注意的事项包括今天安装新的OPC模块以及手动重新启动mySQL

此问题是由位于以下位置的错误文件引起的：

app/code/local/Mage/Adminhtml/Block/Sales/Order/Grid.php

在禁用或重新编译Magento编译器之前，删除或重命名文件无效。要禁用编译器，请从管理面板中选择系统->工具->编译。选择“禁用”以完全禁用编译器，或选择“运行编译过程”以更新所有编译文件

删除并更新编译器后，Sales->Orders网格视图将成功加载，不会出现任何问题
