Go to Virtualmin -> Log and Reports -> AWstats Configuration.
Click on Enable plugins and select geoip. "Save and Regenerate" (because Save is redirecting you to other page - mentioned in other issue recently). Even geoip appears in AWstats report page see is loaded (at the bottom) there are no geoip information on the page. Deselect this plugin in the same page, save and regenerate. AWstats report page have the same content. Selecting/Deselecting this plugin doesn't have any effect.
GeoIP is an important part in AWstats. Could you please check functionality for geoip plugin (the free one)? Do we have to do some changes in code or settings to make this working?
PS - please note in other issues reported that you have to include a perl library for making plugins working. This must be included in AWstats or Virtualmin installations. Up to your decision.
