WordPress instance is broken:
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 `127.0.0.1:3306`. This could mean your host’s database server is down
Incorrect database connection settings in wp-config.php.
1. go to Customer panel > Databases > User management and make sure that the correct credentials are set.
2. Set the database connection credentials and database name in configuration file
3. Make sure that the database exists: Plesk > Tools & Settings > database Servers > MySQL > Databases
