Tag / Search result nothing! Why??

Hi!

I just realize this problem recently. My blog show no search result or tag result when I use the search or click the tag. What’s wrong? It went just fine in the offline, I’ve test it before. Even if I change the theme, the problem still occurs. So, that might be not a theme problem. Maybe it’s a plugin?

My plugin:
Add Lightbox
Akismet
Add Social Bookmarking
All in One SEO Pack
Brian’s Threaded Comments
Dagon Design Sitemap Generator
Dean’s Permalinks Migration
Google XML Sitemaps
Lightbox 2
Ozh’ Admin Drop Down Menu
Page Links To
Post-Plugin Library
Similar Posts
Ultimate Tag Warrior
WordPress Database Backup
WP-ContactForm
WP-Sticky
WP-UserOnline
WP-UserOnline Widget
WP UserInfo Widget
Yahoo Messenger Online Status

Actually I haven’t try to use all of them in the offline version, so one of these plugin might cause the problem. Right now I don’t have enough time to try each of them, so I’m looking help here, hoping someone know the answer.

Thank you before.
Best regards,
