Webmin server daemon error message

SYSTEM INFORMATION
OS type and version Debian Linux 12
Webmin version 2.105

When running the APC UPS daemon and calling it to view status, have recently been getting the following message:

Warning!

It is detected that the Webmin web-server daemon was not restarted correctly on the last package upgrade. This is necessary to restart web-server manually by calling /bin/systemctl restart webmincommand.

Hello,

It means either this third-party module isn’t calling WebminCore or Webmin restart is indeed needed.

Hi Ilia,

I restarted Webmin, but same issue. 3rd part software has not changed, so not sure why this is now showing up. Webmin has updated, so what could I check next to debug the source of this?
