After upgrading Virtualmin to version 3.91.gpl GPL on Amazon AWS amazon linux instance (Amazon Linux AMI release 2012.03) with Webmin 1.580 I get error in the IP address and forwarding section when trying to create a virtual server:
Error - Perl execution failed Undefined subroutine &net::active_interfaces called at virtual-server-lib-funcs.pl line 3457.
Note: Recheck and refresh configuration
gives this error: The Network Configuration module is not supported on your operating system. Virtualmin needs this module to manage virtual network interfaces.
It used to work just fine before the upgrade.
Where do I look to fix this?
