When trying to create a new account for the Whonix wiki I get the following error:
# Database error A database query error has occurred. This may indicate a bug in the software. [33b63f06dfd04c308f8ab5e4] 2020-10-18 17:16:17: Fatal exception of type "Wikimedia\Rdbms\DBQueryError" Retrieved from "https://www.whonix.org/wiki/Special:CreateAccount"
Which seems pretty similar to ‘Creating Wikimedia account fails with database query error.’
