So i switched servers, I had plesk on my old VPS, and the cpanel people moved all of my files to the new vps. Now after pointing my 'a' address and registering my nameservers, my site is blank. But when trying to login wp-admin, im getting this error: 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. Any help ?
