With my first web host, I was able to re-generate my Awstats webstats on the fly, whenever I wanted, by clicking the 'update now' link at the top of the main page. However, when I switched hosts, I noticed that is was gone. I did some digging, and found out how to change the configuration file for Awstats to re-enable the 'update now' button.
Follow these steps:
1. login into cPanel
1a. Open File Manager
2. navigate to /home/username/tmp/awstats/
3. edit the .conf file (e.g. awstats.yourdomain.com.conf)
4. look for this line: AllowToUpdateStatsFromBrowser, set the value to 1 (AllowToUpdateStatsFromBrowser=1)
5. Save the .conf file. When you refresh your statistics page. you will get 'update now' link at the top of the page.
This applies for any subdomain as well.
