Well... sort of: take a look at those "new" cols in my reports: "kB in" and "kB out". Before 1st March, those additional cols were empty. But they are not empty now: now they are filled with extremely long digits. How to get rid of this without having to comment those modules in which I get the "weird" digits? Live demo I use: Webalizer V2.01-10 (Linux 2.6.18-5-amd64) locale: en_US.ISO-8859-15 It seems to be somehow connected with this debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=380060 or maybe you know any webalizer support community out there?
