I attempted to launch Void-bot (which checks a config page on metawiki before connecting to IRC) and received an ambiguous error that the script could not login as Void-bot. I therefore opened a new browser and attempted a manual login and received the specific error (Cannot access the database: Cannot access the database: Unknown database '0' (18.104.22.168)). @John mentioned on IRC that 0 is impossible for a db name. When I view any page later, it treats it as though the login was successful. I do not recieve this error when logging into my main Void account.

Please see upstream task https://phabricator.wikimedia.org/T167354. We want to backport https://gerrit.wikimedia.org/r/#/c/358152/ (https://www.mediawiki.org/wiki/Backporting_fixes#Backports_to_stable.2Fsupported_release) to REL1_29, but using REL1_30 may be a quicker fix.
