Moved to another wiki engine
Once again, scrolling through the application store of my server, I noticed that the application store of my server already has a mediawiki engine. Taking into account how much RAM the docker xwiki container consumes, I decided to install the mediawiki engine and move to it.
I really didn't like the mediawiki engine. Everything is very simple and very difficult at the same time. Everything works and is configured crookedly, and I could hardly figure out what and where I really needed to edit in order to create categories and pages.
To structure the categories a little, I made a main category and made links to the subcategories that I wanted. After that, I enabled the CategoryTree plugin in the engine settings, which does not work as I need and does not show pages in categories no matter how I configure it. The categories themselves are the same pages that cannot simply be taken and attached to a category. I need to take care of the correct names of the pages so that in the future I don’t have to deal with the horror that awaits me from this wiki engine, but I’ll think about that later.
