[Solved] Error displaying the error page: Application Instantiation Error

ApplicationInstantiation
Problem:
The following issues caused this error message to appear:

  • The database username in our configuration.php file does not match that of what is configured on our hosting account
  • The database password in our configuration.php file does not match what of what is configured on our hosting account
  • The database hostname in our configuration.php file could not be connected to
  • Your MySQL server is down


Solution:
In your Joomla configuration.php file, ensure that your database username, password, and hostname match what is set / provided by your host.

// your database username goes here
public $user = 'database-username';
// your database password goes here
public $password = 'database-password';
// your database server name
public $host = 'localhost';

but some issue on cPanel. if you have MySQL server is down
you can follow this command:

ps aux | grep -i mysql

kill your MySQL PID

kill -9 PID-MySQL

and restart your MySQL service

/etc/init.d/mysql restart
