I've try to install a new wp web, but it's impossible. The instalations says:
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.
Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you're unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
(with install.php) but my configuration in wp-config.php is correct.
I have two wp webs and I have make an upgrade and all is working ok, but I don't understand why it's impossible the installation. The host, and the Mysql is right (in fact, the others two websites that I upgraded are working properly.
Please, help me!!!!
Thanks a lot!!
