After doing a fresh install of both install-ns and install-oacs and using the new SSL certfile.pem celtic-arts.org is up and running.
Observation:
The latest config-oacs-5-10-0.tcl file is very clean and works very well. I did not have to make any modifications for the SSL certificate to work nor were there any variables issues found.
This matter is know closed. Thank you Gustaf
Excellent job.
