Duplicating/Migrating to a new server

Hi. I have followed the 'Duplicate Installation' Wiki for duplicating my website onto another server, without success. I think I've done everything right, but when I access my site, no formatting, no images (except my logo), just plain text. I get a 'broken link' error when I attempt to login in with the plain forms, and I've run 'upgrade.php' about 5 times now.

Thanks in advance!
