Could find nothing in /var/log/apache2/error.log

However in /var/log/ispconfig/httpd/polyfidelity.org.au/error.log

Update
Just as a last ditch attempt I again switched off suExec and rebooted the server and I can now access the archives at:
http://tastiger.dhs.org/pipermail/test/ and
http://polyfidelity.org.au/pipermail/committee/
any other links give me a 404 error....
