We were able to connect to the MySQL database server (which means your username and password are okay) but not able to select the database.
The MySQL error was: Access denied for user 'southafr_db'@'localhost' to database 'southafr_drupal'.
Currently, the database is southafr_drupal. The username is southafr_db and the database server is localhost:3306.
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.
