Thanks, Ray; however, my installation was from tarball, prior to there being an SME Server RPM. Something is causing the new 1.4 RPM to bork, but as far as I can see I have removed all references to the tarball version. I will double check the templates tree, but it's likely I will rebuild the box (it's my test system) to ensure it installs on a clean box. That still gives me the issue of getting the new version on to my production system...
