To reproduce: go to a Wikipedia article on https://secure.wikimedia.org/ go to page history follow any link from a time to the article as of that time follow the link called "the current version" preceding the article content Actual result: https://secure.wikimedia.org/wiki/[Title] is displayed, which is a hybrid of Wikimedia's HTTPS-style and HTTP-style URLs. The page says "Wiki does not exist." Expected result: Access the current HTTPS version of the article, with a URL of the form https://secure.wikimedia.org/wikipedia/[lowest level subdomain]]/wiki/[title] rather than https://secure.wikimedia.org/wiki/[title] Example expected results: https://secure.wikimedia.org/wikipedia/meta/w/index.php?title=Wikimedia_principles&oldid=20314 should link to https://secure.wikimedia.org/wikipedia/meta/wiki/Wikimedia_principles instead of https://secure.wikimedia.org/wiki/Wikimedia%20principles https://secure.wikimedia.org/wikipedia/en/w/index.php?title=Permanent_interest_bearing_shares&oldid=245031600 should link to https://secure.wikimedia.org/wikipedia/en/wiki/Permanent_interest_bearing_shares instead of https://secure.wikimedia.org/wiki/Permanent%20interest%20bearing%20shares Note: This affects Wikipedia, but not Wikibooks. I don't know whether this problem is specific to Wikimedia wikis. I couldn't access another Media Wiki site by HTTPS.
I have followed the steps, and the expected result occurs.
https://secure.wikimedia.org/wikipedia/de/w/index.php?title=Wireless_Local_Area_Network&curid=19806&diff=73400394&oldid=73119759 has a link to https://secure.wikimedia.org/wiki/Datei:Ng-WG511-cl.jpg which does not exist in the message notifying about the updated file ("Einige Vorlagen/Dateien wurden aktualisiert: Datei:Ng-WG511-cl.jpg Bitte beachten: Falls eine dieser Vorlagen/Dateien eine gesichtete Version hat, wird diese in der gesichteten Version dieser Seite angezeigt.").
Above issues no longer seem to be at issue. The bit in comment 2 _might_ be something to do with FlaggedRevs; the notification message mentioned above no longer shows there, so can't tell if it's current. (If it is still to be found, please do open a new bug!)
