blank page – add post/edit

Hi, i just moved from a normal server to a vps. I’ve imported my files however when i import my sql database, i see all posts however if i want to edit or add a post, the post body never shows up.

I’ve loaded a backup (older version of the sql) and that seems to work fine, i cant understand what is happening, i disabled all plugins and i even installed a brand new 2.7 wordpress and i get the same problem, blank add/edit post(from admin pannel). Is there any way to fix it?

Also what i’ve noticed is that in some cases its asking me “host info”, can it be somekind of chmod error? (with the backup db it runs smooth no problems). I cant use the old db because im gonna lose about 3 months work =/.

Thanks 4 any help
