This sounds like a missing .htacess file. Please ensure you uploaded everything successfully, including files that start with a dot… these are hidden on a Mac file system. You may need to set your FTP program to show invisible/hidden files.
Hm, a blank page without any error message. Could you either enable debugging or check the server and PHP error logs?
Edit: Looks as if the .htaccess file is ignored. Try and put any random characters in there. You should get an error when opening the page. If not, it is ignored and you would have to change the server settings to allow overwriting server settings through your .htaccess.
