MediaWiki
From The Maceys in California
MediaWiki makes the Macey web go round. It seems like it should be easier but here are some places to visit on a new, or updated, installation.
Comment out the Abuse Filter right up front.
Maps Extension
https://maps.extension.wiki/wiki/Installation
This is probably the one that is the easiest and most complicated at the same time. It really needs to be done from the www-data user. Make sure that the permissions are all correct. and then:
su www-data cd /var/www/html/wiki
COMPOSER=composer.local.json composer require --no-update mediawiki/maps:~10.1
Answer 'n' so that a local composer.json will be created and 'y' to trust.
composer update composer update mediawiki/maps --no-dev -o
