User noted that https://canadianmysteries.ca... threw up a security warning. The certificate is actually on the canadianmysteries.uvic.ca domain and not the canadianmysteries.ca domain (long story involving it being purchased through systems and thus part of the uvic.ca domain name). Got user to try using the http protocol and the domain name with uvic in it, but still he couldn't get through, so I suspect some kind of security setting on his machine or network was also in play.
Ended up sending him the visible text of those files as attachments to an email, so at least he had that, which is all he wanted.
Nobody else has ever complained about this, so I don't think I'll do anything more.
