If you see this error in your webgui.log file
CRON: Response for site.conf-pbcron0000000000000004 was redirected. This should never happen if configured properly!!!
It is usally caused by a mismatch between
the webguiPort specified in WebGUI/etc/spectre.conf
and
the port you are using for the redirect (last line) in your site's modproxy file
If those port numbers are the same, make sure your site's modperl file has that same port number in it's first line (the VirtualHost directive)
