Blocked script execution b/c 'allow-scripts' permission is not set. about community HOT 3 CLOSED

This is most likely caused by extensions which automatically inject scripts into every frame on the page. Could you try to load the page in Incognito mode (without extensions) and see if they disappear?

I'm getting the same errors. Both in regular and incognito modes

Which casts is this happening on? The sandbox warning can happen when people include scripts in the html-part of the example, which is then rendered in the preview. So in that case it's really nothing to worry about, it's just that we don't preparse the html and remove the script-tags when we replay things in preview. The fact that you cannot open the console sounds like a bug though.

If you don't want to share the affected casts publicly you could PM me the link on gitter :)
