Perhaps a little bold to ask, but would it be possible to update the wiki? It's not that I'm missing any features, but the version of mediawiki hasn't been supported since the end of 2014. Perhaps an update to the latest LTS, 1.35, would be nice? That would require an update of PHP to 7.3.19 (current version 5.3.3 was released 11 years ago) and an update to MySQL to at least version 5.5.8 (support of the current version ended in 2011)
Don't forget all the currently installed extensions.
