Hello All,
After looking at [1]Manual:CORS and trying to perform a request with JQuery from an external application, I still get the error message saying "Request from origin has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
This is from a simple GET request to get imageinfo from Commons.
Please any hints? Eugene233
