I've setup php4 on my home machine and tested www-user on it. All pages of our creation works fine without any changes -- simply tell apache that .php3 files get handled by mod_php4 also.
However, there is one snag: the Feedback form. php4 offers an error message of how to fix the error I get running it but it might be better to take this opportunity to replace the feedback form with something a bit fancier. We've discussed before the possibility of a form that included a classification for the feedback so we could send to appropriate addresses (lyx-users, lyx-devel, /dev/null, etc.). Has anyone got any suggestions for a possible replacement? I only had a copy of www-devel from July but it all worked fine and I don't expect there should be anything on that site to cause problems. I'll take an updated copy home and retest just to be sure. Allan. (ARRae)
