csf stopped working in webmin

[Stephane]

If you are using a theme for Webmin (for example Authentic theme), you want to update your theme to the latest version.
Force the latest stable update by going to https://webminurl:webminport/webmin/edit_themes.cgi or clicking on the settings-icon next to your selected theme on the webmin homepage and at the bottom of that page you can choose to force the newest update (pick "stable").

In my case I was on Authentic theme 18.x and was having the issue with CSF not loading. After forcing the update I'm now on 19.03 and everything is working again.

In the change log of Authentic theme I found this line under version 19.02 (November 7):
"Fix to support latest version of ConfigServer Security & Firewall"

Updating the Authentic theme did fix the problem. However, I run multiple servers so is there a way to update the theme through a shell command or script?
