awstat error: couldn't open server log file

Обратился клиент, что ему на почту стали приходить такие письма:

Error while processing /etc/awstats/awstats.conf

Пробовал выполнить данную штуку вручную:
#  sudo -u www-data /usr/bin/perl /usr/lib/cgi-bin/awstats.pl -update -config=domain.com
Create/Update database for config "/etc/awstats/awstats.conf" by AWStats version 7.0 (build 1.971)

Видим аналогичную ошибку.

Совет отсюда: http://linux.koolsolutions.com/2009/10/26/tip-resolving-awstats-permission-denied-error-by-www-data-cron-job/
Не помог.

Тогда я нашел данную статью: http://www.debuntu.org/awstats-error-couldnt-open-server-log-file-logresolvemerge-pl-access-log-no-such-file-or-directory/
# sudo -u www-data /usr/bin/perl /usr/lib/cgi-bin/awstats.pl -update -config=domain.com

Однако и это не помогло.

В конфиге /etc/awstats/awstats.conf
Строку LogFile заменил на /var/www/volgasystem/logs/access.log (лог домена) и о чудо:

# sudo -u www-data /usr/bin/perl /usr/lib/cgi-bin/awstats.pl -update -config=domain.com
