Blank page after migration

Hi all,

I've been trying to sort this out for hours without sucess.

I've migrated from one server to another, just simple copy/paste of files and export/import of mysql database. Next, I've changed everything in settings.php and in database. I'm using 1.2 version. And now everything works except that when I login as admin, I cant go to admin area because i get redirected to homepage. And when I go to settings page I get completely blank page. I've tried increesing upload size in php.ini, but without any sucess.


Any ideas?
