Thanks for the reply!
i checked my php configuration
there it was like this pdo_mysql.default_socket=
changed to pdo_mysql.default_socket=/tmp/mysql.sock as guided by you on screenshot
And restarted vps; Still same error!
Any way adding $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock'; in config.inc.php working fine.
May be error occur beacuse im on Oracle VPS Free Tier!
Soon Wiil try on RackNerd VPS and will let you know how it goes 🙂
