Does ?action=attr fail also?

Often silent failures (blank pages, no errors) is an indication that
there's something wrong with the PHP session configuration.  Try
?action=diag and see if sessions are enabled.

If the system is running on a Windows server then definitely check
the value of session_save_path.  Actually, check it for a Unix server
as well... but it's very common that PHP doesn't set a valid session
save path in Windows.

If that's not it, let us know and we'll suggest some other stuff.
