I have Plesk 8.01 running without problems for the most part. I decided to set up mrtg and have the graphs sent to /var/www/vhosts/mydomain.com/httpdocs/mrtg

this works ok but when I view mydomain.com/mrtg/mrtg.html I get "Forbidden
You don't have permission to access /mrtg/mrtg.html on this server."

The html/png files are there and if I rename the directory to mrtg1, it works and I can view the files.

Error log:
[error] [client 82.x.x.x] client denied by server configuration: /var/www/mrtg/mrtg.html

Any idea why apache is looking for /var/www/mrtg/mrtg.html ??? Makes no sense to me.
