I am attempting to debug why an iframe is not working in our workshop module. It has never worked, and I am uncertain whether the issue lies on our side or with the external source. I am encountering the following error:
Refused to frame <url> because it violates the following CSP directive: "frame-src 'self'".
We have already changed the Content Security Policy (CSP) in Control Panel to allow the given URL, but the issue persists. How can I resolve this CSP directive problem to get the iframe working?
