Please edit "$wgUploadMissingFileUrl" for sv wiktionary changing it to https://commons.wikimedia.org/w/index.php?title=Special:Upload . Purpose: show a more useful message when a user clicks a non-existent file (see https://www.mediawiki.org/wiki/Manual:$wgUploadMissingFileUrl), go directly to "commons" instead of to the dead local upload page. Local uploads have been disabled for a long time (see T9977).
