Updated WP to 2.8 , then I soloved a permission problem of phpbb3. The owner of some files created by PHP is nobody , and the Public permissions of them is 0 ,that means other users can not read them at least, so I  could not backup files via ftpclient and I could not chmod via ftpclient  obviously.

I wrote some codes,

<?php
$sign=chmod(‘filename’,0644);
echo $sign;
?>

Then uploaded it to the directories via ftpclient and  ran them via web browser, all things became OK.

wordpress还有这样的礼遇。话说，某晚，突然发现有个帖子被疯狂的评论，10分钟之内剧增到40个评论，遂感不妙，被垃圾评论盯上了，而且一个评论一个IP，连mail 都不同。赶紧到网上求援，于是装了Akismet插件，总算拦截住，第二天早上一看，乖乖，看统计

Akismet has protected your site from 170 spam comments already, and there’s 160 comment in your spam queue right now.

这要是靠我手工删还不把我累死？于是赶紧关闭了那个帖子的评论功能。话说Akismet安装时还需要个code到wordpress展上申请，不过发现居然打不开页面，最后翻墙过去，无语。
