Getting intermittent 403 Forbidden errors

[dstanley]

I am getting intermittent 403 forbidden errors when browsing a domain.

One minute the site works fine, another I get a 403 page; Forbidden. This domain has its own static IP and is currently using the default plesk SSL cert.

In the logs it shows;
[Thu Dec 04 12:57:17 2008] [error] [client xx.xx.xx.xx] client denied by server configuration: /var/www/vhosts/domain.com/httpsdocs/admin/images/template/cell_bg13.gif, referer: https://www.domain.com//admin/includes/stylesheet.css

Any idea how to solve this?

The permissions on httpdocs & httpsdocs were 705. I have changed to 755 to see if there is any improvement.
