I just tried installing development version 2004010800 (as a new server starting with an empty MySQL database). Everything went smoothly, with no errors reported until the stage where the admin user is supposed to be created. At this point admin/user.php returns an empty page to wit:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<META http-equiv=Content-Type content="text/html; charset=iso-8859-1"></HEAD>
Is this a bug or am I doing something stupid?
