Two possible warning messages on Special:RenameUser are: MediaWiki:Centralauth-renameuser-merged (appears when oldusername is attached to a global account) MediaWiki:Centralauth-renameuser-reserved (appears when newusername is reserved for the global account owner) Instead of substituting the corresponding usernames, it says User centralauth-renameuser-merged has been migrated to the unified login system. Renaming it will cause the local user to be detached from the global one. User $2 is reserved for a global account. Using uselang=qqx it suggests that the wrong parameters were passed: (centralauth-renameuser-merged: centralauth-renameuser-merged) (centralauth-renameuser-reserved: centralauth-renameuser-reserved) See example below: https://en.wikipedia.org/w/index.php?title=Special:RenameUser&oldusername=Bencmq&newusername=Misaka13645
