As seen at [1], the user (and only the user) of the latest revision of [[pl:Template:Syjonizm]] has been hidden.
Since it was an anonymous edit (by an IP address), the version was unrevieved (pl.wiki has FlaggedRevs enabled); but now trying to review it is not possible (it claims that such version does not exist; the message is in Polish even when I use uselang=en, so I can't quote it).
Additionally, the rollback link says "rollback 0 edits".
