Hi @alzbithkhan123
Did you make the necessary database connection changes in the wp-config.php file?
Usually, you can find the login details around line 20 in the wp-config file.
In this example the current details are:
define(‘DB_NAME’, ‘youDBName’);
define(‘DB_USER’, ‘youUser’);
define(‘DB_PASSWORD’, ‘********’);
define(‘DB_HOST’, ‘hostName’);
