I have an old Linux web host server that I have been using for several years. The technology behind it is old but I want to stay with it because I was grandfathered in and, in spite of numerous upgrades to the host, my particular cost will not be raised unless I ask for an upgrade to the system, and it's a really really good deal.
So, here is what I'm working with:
I would like to install a wiki software that still uses these technologies.
Can you recommend a good one?
