Hello! To my surprise I found out that awstats is showing all data two days in the past. I really don't have the slightest idea what could cause this. Awstats has been installed in the course of the perfect server setup. I would be very thankful for every idea how I could approach this glitch. thank you & have a nice weekend!
Most likely the timezone setting in /usr/local/ispconfig/server/lib/config.inc.php is wrong. Change it to match your timezone.
Indeed, this was it! (it was originally set to UTC) Thank you Till for having kept track on this one, very appreciated!
