I've migrated from apache to nginx and managed to make everything work, except for AWstats.
If I enable AWstats from the "Edit virtual server" menu it shows the error: "Failed to create virtual server : AWstats reporting cannot be enabled for a server without a website" . Same issue if I create a new virtual server with AWstats and Nginx enabled.
I could make AWstats work separately from Virtualmin and access it from http://your_domain.com/cgi-bin/awstats.pl?config=your_domain.com, but I'd really like to have it functional through Virtualmin.
Using webmin 1.782 on a centos 6.7 VPS.
