Undefined subroutine &virtual_server::sort_indent_domains called at /usr/share/webmin/virtual-server

Hi,

One of our clients was trying to create a new email account today on a virtual server and received the following error:

"HTTP/1.0 500 Perl execution failed Server: MiniServ/0.01 Date: Tue, 23 Sep 2008 15:01:59 GMT Content-type: text/html Connection: close
Error - Perl execution failed

Undefined subroutine &virtual_server::sort_indent_domains called at /usr/share/webmin/virtual-server-theme/left.cgi line 89."

I have had a look around and can't seem to find anyone else having this problem.

Can anyone advise on how I can fix this.

We are using Virtualmin Pro 3.61 on Ubuntu 7.10

This is quite urgent as it has left us unable to perform any other virtualmin tasks.

Thanks in advance.

Martin
