I have the same thing on Firefox 8.0 running on Linux (Fedora 15); the
error "Virtual host not found on this server" appears, yet Firefox 8.0

Ignore me. I'd put "http://gridwatch.templar.co.uk" in the non-working
browser and "http://www.gridwatch.templar.co.uk" in the working one.

Suggestion: under the line "ServerName www.gridwatch.templar.co.uk", add
an alias "ServerAlias gridwatch.templar.co.uk" in httpd.conf.
