Refresh needed for wp

Hi! I have installed a wp on DH but some problems arised. Almost everytime I entered in a blank screen appears first and I have to refresh to load the page then. it runs on a subdomain but others run fine. I know that mysql runs on another machine so prehaps it slows down wp somehow, but it should not be the all, right? I left most configures as default, php5 but no fastcgi. anyone who found the same problem? or could give me some suggests?

i dont think it’s a problem of wp so i post it here. thx!

update: fixed! I just disable wp-cache and then it works fine.
emmm…seems wp-cache is kind of imperfect…

Here the fix which involves a little patch to make WP-Cache work with PHP5.
