If you would still like to see a breakdown of countries then you need to edit the 'webalizer.conf' file inside your webalizer stats directory. Please add the following two lines:
If you see the following already there then just delete the "#" there ie:
# DNSCache dns.cache
# DNSChildren 1
Remove the # and space after.
If the file doesn't exist, you can create it.
Please note that this will not have any effect on any existing log files and will only update new files created after the amendment.
