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 ‘’ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.


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…
