You may have noticed today that video embeds from YouTube are no longer working in Apostrophe. This is actually due to a YouTube bug: their video pages are issuing
http: meta tags for oembed discovery, but the use of those
http: URLs results in a 403 error because only
https: is not allowed.
We have issued an update to the
oembetter package to address this. If you
npm update your apostrophe project you should get that fix.
