One client had issue with Awstats statistics. They stoped working. When he tried to add new domain and check Awstats in cPanel, this message was shown:
There are no domains which have awstats stats to display
Awstats were configured correctly, cron was executed. I then discovered that there were no active access log in /usr/local/apache/domlogs/domainname.com. So I tried to tail this log while visit web site, no access log was generating.
A while ago I enabled cPanels option “Piped Log Configuration” which was suggested to enable to speed up cPanel control panel experience. When this was disabled, access log per domain started to working again.
