Hello,
I'm trying to perform CORS requests but everytime I try I face this error:
Cannot load "services provider site". Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'my domain' is therefore not allowed access.
I tried modifying the js code of my site, I tried modifying the .htacces but nothing. I entered the Access-Control-Allow-Origin in many different ways. Is there a way to modify the server settings and configure the requests header? How can I modfy my requests' header?
Thank you very much for your help
