After autoupdate from 1.550 to 1.560 Webmin dont start at boottime. When I select yes, start at boottime in Webmin-configuration and I click on save, the select switch to no. If I select at start/stop in system webmin and select start at boot the change will not be activated. So after reboot the webmin not startet. All I can select I have tried, - but nothing is work. So I think it is a bug.
I used Ubuntu Server 10.04.2. With Webmin 1.550 it works perfectly. The problem comes with version 1.560.
