Hello,
I don't have the new tab to export a local file to Commons.
For example, I want to move [https://ko.wikipedia.org/wiki/%ED%8C%8C%EC%9D%BC:Mujujeja1.jpg this file] from wp:ko to Commons, but have no "Export to Wikimedia Commons" tab. It doesn't work either in any other language.
The documentation says "FileExporter is now a default feature on all wikis." so I guess I should not activate anything in my preferences, but can you see what could I do?
Thanks.
