That's how the path should look (it's to help caches and proxies), although I use a more conventional path on Windows servers because of errors like you describe. Is your server on Windows? Perhaps the Windows detection isn't working (all I do is check for the existence of a $WINDIR environment variable).

Can you guys all check your PHP version?

As I've written in the Install doc (under requirements), you NEED to have 4.1.0 or later. Anything before that does not support the $_SESSION variable, and this will cause the admin login to fail exactly as described.

BTW, Bob told me in email that this DirectoryIndex setting fixed his problem.

I need more information to solve this...

- do you have cookies turned on in your browser?
- have you checked the DirectoryIndex setting in Apache?

If yes to both, could you please delete your Moodle tables and send me a URL and your config.php so I can go through the setup process myself?

Cheers,
Martin

Just checking: you do have cookies turned on, don't you?
