Display my app in heroku and some icons do not load, I get this error ...
Access to Font at ' link ' from origin ' link 'has been blocked by CORS policy: No' Access-Control-Allow-Origin 'header is present on the requested resource. Origin ' link ' is therefore not allowed access.
I have several functions with ajax which do not work either ... all this in local works correctly. What I do?
Response to preflight request does not pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
