Jonathan pointed this out to me while remove a link from the installation documentation to the no longer existing old.html page.
At first I was puzzled, but a bit of debugging made me realize where the (now) empty old.html page still was coming from. Fixed thusly, and I'll add some code to detect such situations should they ever occur in the future.
