Description:
All Wikivoyage wiki's display "Fatal exception of type MWException" when I try to log in. Anonymous browsing is OK, though. I can also browse Wikipedia, Commons and other WMF projects when logged in. This problem appeared half an hour ago and correlates with the latest update of the MediaWiki software.
Version: wmf-deployment
Severity: major
