Hello,
I installed Moodle 1.5 on a server I use for testing software. I originally had installed Moodle 1.4.4 succesfully. I did this s few times just to make sure I got the hang of it. There were relatively few problems when I installed 1.4.4.
I removed 1.4.4 from my server and I dropped the entire database.
Now I am trying to install 1.5. I tried a few times and I still get the same errors. When I go through the initial install.php through my browser, I never get the page for the admin user and password. Then, when I finish the process, it automaticilly goes to the login screen. Then, when I try the username admin and password admin it keeps jumping back to the login screen.
