The code for vihistory used "<?" to open all the php blocks. Newer versions of php and our server infrastructure require "<?php", so I've replaced all the instances that needed to be changed. Also made changes in protocol from "http" to "https". NB for both of those, there are a small number of instances (e.g. <?xml and http used in headers) that must remain as they were, so a simple global search and replace is not possible. Site seems to work at e.g. webserver2.hcmc.uvic.ca/~taprhist/search/searchcensus.php and hcmc.uvic.ca/~taprhist/search/searchcensus.php
