[...] 前段时间给主机上的几个wordpress都升级到了2.8，结果全部出现了不能添加已有标签的问题。一开始以为是DB Cache之类的插件的问题，但禁用了所有插件后依然不能添加tag。经过漫长的寻找后终于在这里找到了解决方法，即将wp-content目录下的db.php删除或改名即可。有人知道db.php这个文件是哪里来的吗？…… [...]

Same problem after upgrading: the tags were out. I will look at your solution.

Little weird..

I was upgraded mine manually also.. as dunno how to auto-upgrade it.
installed brand-new 2.8 into a new folder..

edited the config.php to reflect the old one..

then moved all my file under old one
( under wp-contents -uploads, plugins, themes)
into a new folder.

then.. it seem ok.
until i want to login into administrator mode..
just need to press one button .. to upgrade database..
and it is done.. after that..

This is why I have a dummy duplicate blog with all the same addons installed, the same widgets on the side, an identical theme and so on with some dummy posts ala wp-themes.com.

I run my upgrades there first now.

That is quite strange. I was able to update my wordpress to 2.8 manually without a hitch. I even double checked that I could save tags when I saw your tweet about it.

Are you using/have you ever used DB Cache? This post seems to match your tag issue, but not the upgrade one:
http://wordpress.org/support/topic/275443

Also, DB Cache seem to be the only WordPress plugin which creates a db.php file.

(An (unrelated?) plugin, HyperDB, contains a db.php, but looks nothing like the one you pastebin'd)

I know there is a condition in wordpress to load that db.php if there is no MySQL found. If you ever used a different database you would have had to add that db.php file in order for wordpress to speak to the database. No idea how you would have wound up with that file.

That sounds a little odd. My wordpress upgrade went fairly smoothly (apart from a little bit of stupidity by me that meant I needed to restore from backup and re-do the automatic upgrade)

The only thing i'm not so happy about is on the Fusion theme I was using, the right hand widget column now mysteriously started appearing half off the page on the bottom left. Very odd, couldn't fix it by repositioning it and couldn't be bothered to faff about with the template, so just switched to another one.
