Since last week in elwiki "Cite" button (cite-ve-toolbar-group-label) and the "Add a citation" title are displayed in English. They are properly translated in translatewiki and the translation is present on wiki: https://el.wikipedia.org/wiki/MediaWiki:Cite-ve-toolbar-group-label and it was displayed correctly in VE. I can't find what happened. Can someone think something before I report a bug in phab?
