尝试在浏览器中打开 Parallels Plesk Panel 时您会收到以下错误: "HTTP Error 503. The service is unavailable."
Parallels Plesk Panel 会使用 IIS 作为 Web 服务器。
IIS Advanced Logging
IIS Mod-Rewrite 安装在服务器上:
第三方 ISAPI 过滤器在 PleskControlPanel 网站中注册的截图如下:


Plesk 默认的应用程序工具在重启后崩溃并出现如下错误:

Log Name:      System

Event ID:      5139

Computer:      Test
A listener channel for protocol 'http' in worker process '3768' serving application pool 'PleskControlPanel' reported a listener channel failure.  The data field contains the error number.

为 PleskControlPanel 网站配置的 ISAPI 过滤器引起的,该过滤器不能与 Parallels Plesk Panel 重写过滤器一起运行。
