We need implement in our website a button to allow the logged users to register into a webinar
But I get this warning message in the console (firefox): Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
Please, could you tell me if is possible implement this functionality and what are the steps that we have to do?
Many thanks in advance
