Unable to connect to database server
If you still have to install Drupal, proceed to the
installation page.
If you have already finished installed Drupal, this either means that the username and password information in your settings.php file is incorrect or that we can't connect to the MySQL database server. This could mean your hosting provider's database server is down.
The MySQL error was:
Too many connections.
Currently, the username is
xxxx and the database server is
localhost.
- 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?
