referer in apache logs not seen in awstats

Trying to set up awstats for one of our servers which needed referer information to be captured - the referer info was not being displayed initially.

Documentation said

https://www.awstats.org/docs/awstats_config.html#SiteDomain

better to have separate logs for each virtual server. So, set that up.

Purge old files (which contain irrelevant data during testing) by deleting from DirData

AWStats Documentation - Configuration directives and parameters

https://www.awstats.org/docs/awstats_config.html#DirData

It is in /var/lib/awstats on our server.

And the main reason for referer not being displayed was the wrong logformat - it needed to be 

LogFormat=1

and not 

LogFormat=4 # default
