I recently create a domain, let say example.org then I realize it should be example.com and decide to change domain name from WebGUI.
Everything went fine but backup stops.
It is the same as http://www.virtualmin.com/node/27328
and I found that the /etc/logrotate.conf was not up to date with new domain example.com and still looking after example.org_access_log and example.org_error_log
my setup is Debian Squeeze 64bits Webmin 1.630 Virtualmin 4.01 GPL
Here is the email result of the backup where it says the backup were completed in 0 second
