CORS policy and rum


since i transfered my domain to Cloudflare registrar and I put the script of Analytics I have the following error

Access to XMLHttpRequest at ‘’ from origin ‘’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: The ‘Access-Control-Allow-Origin’ header has a value ‘’ that is not equal to the supplied origin.


What do i need to do?


Sounds like it’s because you are accessing your localhost website in port 8000?

yes because i’m using a django framework and we access on this domain the localhost website
