I've put WP on my computer with Xammp etc. When I do the last step of typing in http://localhost/wordpress/wp-admin/install.php in my browser I get this message:
Error establishing a database connection
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.
What should I do? The username and password are as per instructions in http://www.tamba2.org.uk/wordpress/xampp/
Help is greatly appreciated.
