Creation of staging enviroment fails

I can’t create a staging site.
When I enter the subdomain “” it gives me the following error message: “Failed to create child-domain for staging enviroment. [404]”
I tried it with several domains and subdomains. Doesn’t work. Always the same error.

Maybe someone has a hint what to do?

OpenLiteSpeed 1.5.7 and Cyberpanel 1.9.1 running on CentOS Linux release 7.7.1908 (Core)

Do you see anything in main log file of CyberPanel ?

Problem solved.

Just for the record:
Log-file told me:
“[10.29.2019_13-50-57] [Errno 2] No such file or directory: ‘/etc/opendkim/KeyTable’ [setupDKIM:275]
[10.29.2019_13-50-57] [Errno 2] No such file or directory: ‘/etc/opendkim/KeyTable’ [createDomain]”

so I did some googleing and installed dkim.

Now it works.
