On wikitest looking in https://test.wikipedia.org/wiki/Special:LanguageStats page me a message appears in red background and does not make me see the translation table. In this moment there are mobile devices with the view to Deskop (I'm using google)
The error text:
[WKIPEwpAADkAAjFyvIMAAABG] /wiki/Special:LanguageStats BannerExistenceException from line 348 of /srv/mediawiki/php-1.29.0-wmf.11/extensions/CentralNotice/includes/Banner.php: No banner exists where tmp_name = WikiCon. Could not load.
