there are 4 values that must be set correctly in the file wp-config. Normally they are the first 4 values
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
/** MySQL database username */
/** MySQL database password */
/** MySQL hostname */
the first 3 you can determine from this page https://panel.dreamhost.com/index.cgi?tree=goodies.mysql& in the panel. (click the username on that page for password information).
the 4th value (hostname) appears to be set correctly as mysql.pointsforgood.org
