At the top of the preferences - Geolocation page there is is this message:
In order to use Geolocation, please download this file and extract it (using Winrar or Gzip) into the /tools/geoip/ directory.
However there is no geoip directory in tools. There is one in vendor. And that has another file in it named geoip. Please see the screenshot below. Should I put the Geolitecity.dat in the first one, the second one or create a file geoip in tools?
I created the folder but I then got a theme problem so I took it away again
