Unable to connect to database server
This either means that the username and password information in your settings.php file is incorrect or we can't contact the MySQL database server. This could mean your hosting provider's database server is down.
The MySQL error was:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2).
Currently, the username is
username 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?
