Today the "Wikidata generic tree" tool is not able to load the labels. My Chromium console reports:

[Report Only] Refused to load the script 'https://d3js.org/d3.v3.min.js' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-eval' 'unsafe-inline' blob: data: filesystem: mediastream: wikibooks.org *.wikibooks.org wikidata.org *.wikidata.org wikimedia.org *.wikimedia.org wikinews.org *.wikinews.org wikipedia.org *.wikipedia.org wikiquote.org *.wikiquote.org wikisource.org *.wikisource.org wikiversity.org *.wikiversity.org wikivoyage.org *.wikivoyage.org wiktionary.org *.wiktionary.org *.wmflabs.org wikimediafoundation.org mediawiki.org *.mediawiki.org wss://tools.wmflabs.org". Note that 'script-src-elem' was not explicitly set, so 'default-src' is used as a fallback.

Same result with FireFox.

Thanks for any support that anybody can provide

Ciao
