Ispconfig3: awstats/webalizer not working, client web logs empty

If awstats or webalizer is not containing any data and the client web logs are empty, the cause might be missing mounts of the log directories in /etc/fstab.

Search /etc/fstab for the client domain name. If no log mount is found, add a line for the client web site manually in this form:

/var/log/ispconfig/httpd/DOMAIN.COM /var/www/clients/clientNNN/webNNN/log    none    bind,nobootwait    0 0

After that do:

mount -a
mount

to verify it is mounted. After nightly cron, check that awstats or webalizer contains data.
