If you want webalizer or awstats pages to be available by default for new domains, you can do so by creating:
/usr/local/directadmin/scripts/custom/domain_create_post.sh
In the file add the code#!/bin/sh
ln -s ../stats /home/$username/domains/$domain/public_html/stats
exit 0;
If you want it to be for awstats, then change the bold stats name to be awstats instead.
