okay seems you've deleted cwp root_db kindly take your files and db backup and reinstall the server.

I reinstall 4th and new install but still this the same error.
p/s: I install OS: centos 7.7 version 1908 run script on site http://centos-webpanel.com/cwp-installation.

if you're unable to install it you can request installation support
