So I was messing around with ManageWiki because I'm trying to improve it's documentation page https://meta.miraheze.org/wiki/ManageWiki. I temporarily set all users (group *) to not be tracked trough Matomo (permission noanalytics) and since that I get the error below on all pages:
Database error
A database query error has occurred. This may indicate a bug in the software. [6e112fb964a201f6b8fbb072] 2018-11-03 04:32:16: Fatal exception of type "Wikimedia\Rdbms\DBQueryError"
Tried to change things back but with no luck.
