Just in case you’re using Mailgun with Mediawiki…
The docs don’t cover this, but the steps in this post got it working for me:
- Install composer
apt-get install composer
- Run
composer update
from theextensions/Mailgun
folder - Run
php maintainence/rebuildLocalizationCache.php
from the main mediawiki folder.
Running your own services get you into all sorts of fun trouble like this.
