I want to setup Identity Server as SSO provider for my DRUPAL website, according to this URL :
https://medium.com/@iwantha/wso2-identity-server-sso-with-drupal-8-4bb8ae915c20
However, when I came to "Configuring Service Provider" section :
My Identity Server gives a blank page for the "Add" button (/carbon/application/add-service-provider.jsp)
