I have ISPConfig 2.2.6 with Webalizer installed. stats folders are created in all sites' roots, but they are empty, with the exception of .htaccess files. What I see though is a directory /var/www/usage that has up to date stats, but, obviously, I cannot access it via browser. And it looks to be server-wide and not specific to any site in particular. Can I create a webalizer.conf for each site?
