When clicking on an image, I keep getting https://commons.wikimedia.org/wiki/File:Undefined
Is there a way to link the file description page?
Thanks for the report. You should get to the file description page when clicking it. For some reason the link is wrong.
@Jonas, I made an edit request at https://www.wikidata.org/wiki/MediaWiki_talk:Gadget-ImageHeader.js.
Thanks. The fix works for me.
