Was this a new installation of the smokeping package or an upgrade from
an earlier version?

I put quite a bit of effort into getting this right in the package,
and I'd love to find out what went wrong for you.

I have no idea where this is coming from. Please include your 
/etc/smokeping/apache2.conf and /etc/smokeping/config.d/pathnames.

Some background: earlier versions of the package installed the web
side in /var/www, but as this was a violation of the Debian policy
(and the Filesystem Hierarchy Standard) they now (as of 2.3.6-4) go in
/usr/share/smokeping and /var/cache/smokeping/images.

The Apache configuration snippet in /etc/smokeping/apache2.conf (which
should be symlinked into /etc/apache2/conf.d) makes Apache look in the
right place, and upgrades from earlier versions also add a few symlinks
in /var/www to try and keep things working.

Reinstalling it probably doesn't change anything. If you're prepared to
lose the measurement data, you might want to try 'dpkg --purge smokeping'
(which removes all the config files and data) and reinstalling afterwards.
