What is the Zend Optimizer?
The Zend Optimizer is one of the most popular PHP plugins for performance-improvement, and has been freely available since the early days of PHP 4. It improves performance by taking PHP's intermediate code through multiple Optimization Passes, which replaces inefficient code patterns with efficient code blocks. The replaced code blocks perform the exact same operations as the original code, only faster.

In addition to improving performance, the Zend Optimizer also enables PHP to transparently load files encoded by the ZendGuard.

The Zend Optimizer is a free product available for download from Zend Technologies. Zend Technologies developed the PHP scripting engine, also known as the Zend Engine.

默认好像就是安装好的，你也可以自己安装一个试试。

本来是正常显示 的，不过如果自己安装远程的话应该安装在根目录下吗？

本来是显示正常的？不明白，默认安装好的，你现在要重新安装吗？你安装的是什么程序？

trt

系统是PHPCMS3.0的，网站先前是正常运转的，能正常显示页面，今天才出现此提示。

该如何处理？
