Normally, when you download the source code of the index.php it means that php is not working…

What is strange that you get exactly the same messages after the upgrade, so php must be running and there are no new errors. Did you upgrade your system shortly after? Are the php-fpm-processes still running? Any errors in your web-server-error-log?
