Blocked by CORS policy: No 'Access-Control-Allow-Origin' header

Hi, just a notification about this error message on my Publish site (from Chrome console):

Access to XMLHttpRequest at ‘https://publish.obsidian.md/cdn-cgi/rum?’ from origin ‘https://lab.marconoris.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

POST https://publish.obsidian.md/cdn-cgi/rum? net::ERR_FAILED 200

Without publish.css and publish.js neither…

what’s the problem? Is the site not working?

Hi WhiteNoise, the purpose of my message was just to notify the error… I don’t know if there is another better place to do it (and if this isn’t, I apologize and ask you where I can direct this type of information). I have no technical knowledge of this type, so I don’t know if this type of error can cause some issues, such as not being able to embed mp4 video on a page… for the rest, the website works great…
