Here’s what the error looks like:
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.
Now, with the password hidden, heres what’s in my wp-config.php file:
DB name is wordpress
user is wordpress
the password is exactly as I set it
host name was blank, changed it to localhost. It didn’t work blank either.
