I had the same problem. I changed the PHP execution mode to CGI (not FGCI) and -while it stills leave me on a blank page with just a title-, the execution continues in the background. So if I hit Reload in the browser, eventually it will show the last page of the configuration, asking me about the parameters for the admin profile.
So, just left alone Moodle a while installing, ignoring the white page for about 5 minutes, then reload the page. You can reload it as many times as you wish until it becomes available again.
