blank admin page and broken update script

The admin panel page is blank after update. I check the log and get

[error] 12675#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error:  <br>The encoded file <b>/usr/local/cwpsrv/htdocs/admin/login/index.php</b> has expired. in Unknow
n on line 0" while reading response header from upstream, client: xx.231.192, server: localhost, request: "GET /login/index.php HTTP/1.1", upstream: "fastcgi://unix:/usr/local/cwp/php71/va
r/sockets/cwpsrv.sock:", host: "xxxxxx:2087"

After this i try to run the update script and got this.

It seems that you didn't upgrade the cwp panel when it needed the manual upgrade, so you missed some important stuff. I think that the only way is to reinstall the operating system.

Make sure that you will backup your files using FTP, the phpmyadmin and files from /var/vmail/, then reinstall the operating system along with the new cwp.
