Enabling W3 Total Cache cause dashboard to be blank

Hi, I use WP 3.0.3 on byethost.com, my site has W3 Total Cache with about 10 other plug-ins, including Highlight, Google Sitemap XML, Syntax Highlight, Delete Revision,…

W3 Total Cache is great, but every I access dashboard I only get blank page. (I’ve checked by turning on and off each plug-in one by one). I got a way around it: access the dashboard by other section, such as “posts” or “comments”. All the main function of the dashboard can be shown that way, but if I can normally access dashboard that would be much better.
