WordPress MU

We have been having all kind of problems trying to install wpmu.
This is our latest error and we cannot resolve it........
"This either means that the username and password information in your wp-config.php file is incorrect or we can't contact the database server at localhost. This could mean your host's database server is down."
We know our database server is localhost and I actually went in and made a new database to ensure our username and password information was correct and we still get this error.
Can anyone assist me with this? Any ideas?

Don't edit the config file manually. let WPMU create it for you.

I haven't edited the config file and I still get that error. Any other tips?

Get someone else to check for typos?

That error is displayed because it can't get to the db server, or the user/pass is not correct.

Does the user have ALL permissions on the db?

Ok, I started it all over and my install was finally a success.
I am having another problem now though. When I logged in to admin it now shows "Index of /wordpress-mu/wp-admin" and it lists all the files.
Also, when I go to our website address it also just shows the index files.
Any tips on this???

You're server's not set to execute php files?

Either that or it;s not setup to see index.php as an index file.

The issue is with the wp_config file in the wp_content folder.

fast fix:

1. delete wp_config file
2. WP will prompt you to set up your blog site again
3. Enter the username and password of your original database
4. WP will create a new wp_config file and reconnect to your database

you should be good to go.

Well, someone put that in the wrong place. Because it doesn't do that.
