菜鸟求助：apache 中的 SSI 问题（已解决）

环境：
redhat as 4.4 使用 rpm包安装 apache 2.0 +php4+mysql4.1
网站为 php 和 shtml 的

apache SSI 相关配置

<Directory "/var/www/html">
    Options Indexes Includes
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
虚拟主机配置

<VirtualHost *:80>
#    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot /var/www/html/xxxx.org.cn
    ServerName www.xxxx.org.cn
    ErrorLog logs/xxxx.org.cn-error_log
    CustomLog logs/xxxx.org.cn-access_log common
</VirtualHost>

现象：service 运行php其他网站正常，但上面的虚拟主机对应的网站，配置好SSI后，运行ok了，但今天不知道什么原因显示有问题了。

部分报错日志

[client 121.29.176.89] PHP Notice:  Undefined variable:  usr_flag in /var/www/html/XXXX.org.cn/new_xxxx/inc/ifr_login_index_wynn.php on line 50, referer: http://www.xxxx.org.cn/new_xxxx/index_wynn_div.shtml
[client 121.29.176.89] PHP Notice:  Undefined variable:  usr_flag in /var/www/html/xxxx.org.cn/new_xxxx/inc/ifr_login_index_wynn.php on line 56, referer: http://www.xxxx.org.cn/new_xxxx/index_wynn_div.shtml

从贴出的虚拟主机部分的配置文件来看 没有什么问题，但是log 贴的太少，不能看出具体问题根源。建议贴上系统的 log 和 apache 的 error log 文件来进行分析。

apache 的 error 如下

只是如上的重复，没有其他的信息。

俺对 php 也不是熟悉，看日志，Google了 一下，觉得php的代码应该是有问题。
请楼上的看看

俺总以为是SSI 的问题，今天自己仔细在虚拟机上把那个网站的代码挂上去测试了一下，发现是网站代码写的时候一些不规范（我只获得了网站源代码,没有任何说明文档，对码代码有不熟悉），虚拟主机需要特别的一些配置，还要根据报错的日志，对一些目录和文件修改权限。真是晕啊。谢谢 liang3391 兄的回帖啊。
