I followed the guide from here Skin Customization for CyberPanel - CyberPanel
after that a problem like this arises : Redirecting to /bin/systemctl restart gunicorn.service
Failed to restart gunicorn.service: Unit not found.

how to fix it??
I use Centos 7 and the latest version of Cyberpanel.

hello no one wants to help me??

the skin is not updated for latest release, please upgrade your cyberpanel again so it will overwrite the skin and don’t download the skin anymore.
