一个离奇的403 error.URGENT!!!!

在linux上unzip了www.phpbb-seo.com提供的smpl_phpbb3_mod_rewriteV0-4-2.zip后，就登录不了我的论坛了，出现“You are not authorized to view this page”错误。在unzip该压缩包前，我的论坛是正常运行的。
将压缩后的文件全部删除后，还是如此。重启机器，apach都没有解决这个问题。

也检查了apach的httpd.conf文件，都设置了Allow from all.

实在找不到问题所在了，有大侠能解决否？

非常感谢。

我的论坛架构是（apach+php+mysql）

先贴个log看看，和这个authorized to view相关的
