Try this:
stop awstats from the server-manager panel
delete the file /var/log/httpd/awstats_pos (which contains a pointer to the last scanned line of the apache log file)
Then restart awstats. Awstats then will re-scan the apache log, and generate
a new awstats_pos.
To avoid double recorded hits in the statistics, you may delete the apache
log file and restart apache before restarting awstats. But then you will
miss a few hits.
