The list of languages appears
No list of languages appears. No matter how many times you try or reaload. In fact MediaWiki:Gadget-purgetab.js doesn't even show up at the end of the process as usual. A null edit in the page header doesn't change anything either.
The Wikidata part works, see "Català" at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical) and https://www.wikidata.org/w/index.php?title=Q4582194&diff=180524878&oldid=175798508
