我刚刚使用下面的代码卸载了 Litespeed，但是当我尝试通过 httpd 启动 Apache 时出现错误。我能做什么？
这是我使用的命令：
root@s15430558 [~]# /usr/local/lsws/admin/misc/uninstall.sh
WARNING:
All sub directories under "/usr/local/lsws"
created during installation will be removed!
However, conf/ and logs/ can be optionally preserved.
If you want to preserve any file under the other sub-directories created
by installation script, please backup before proceeding.
Manually created sub-directories under "/usr/local/lsws"
will not be touched.

Uninstalling rc scripts ...
[OK] The startup script has been successfully uninstalled! …我每天都会收到这些电子邮件（在我的 cPanel Linux Cent OS 5 服务器上），但不知道它们的意思或做什么；

我怎样才能轻松排序？我有完整的 root 和 SSH 访问权限
