if it’s not helpful than check your PHP configuration file (php.ini) to ensure the MySQL extension is enabled.
Look for a line like extension=mysqli or extension=pdo_mysql and make sure it is not commented out (i.e., no ; at the beginning of the line).

The website works for me without any problems. Have you solved it yet? If so, how?
