I think I have got to the point where I must upgrade my wiki server because functionality that I use is no longer working. Normally I scavenge for new content by adding updated sites to my neighborhood and then view recent changes. I am seeing an error for the activity plugin used by Recent Changes indicating that sites won't show. I can't upgrade the wiki software because the latest releases require the latest Nodejs that is now only available on 64-bit operating systems. I've known that I should migrate/upgrade the server to a more current version of Ubuntu but have been avoiding doing so, but now I appear to not have any choice.#
