Jay, so even it creates all tables and loads the database, you think there is a credentials problem? Also, the installation seems to be crazy picky about the file permissions. Unless I change the config.php to a 777, it does not even load anything but only shows a 500 error. So, even that 3rd phase does not finish, I can trz the oc-admin, but then there is not even a logon button, just the text fields....
What PHP version do you use to test it?
