Sometimes it happen that the domain is unable to update its webalizer stats. The webalizer for a single domain can be updated with following steps:
cd /home/USER/tmp/ cp -af webalizer webalizer.old cp -af webalizerftp webalizerftp.old cd webalizer /usr/local/cpanel/3rdparty/bin/webalizer /usr/local/apache/domlogs/domainname -n domainname /scripts/runweblogs USER
The webalizer should now be updated for the domain.
