OK .... Ignore the first post. I manage to find the template for the Vhost_ispconfig.conf file.
Like I said, I am trying to use Awstats with ISPConfig. I hope to be able to do this with separate logfiles for every virtualhosts. Once I manage to get Awstats to work, I will post it in this forum and hope that it will help everyone else who are trying to get Awstats to work with ISPConfig.
