Keycloak 19+ KNOWN ISSUE:

New Theme breaks custom providers, to overcome this problem, follow these steps:

• Click "Realm Settings" on the left menu
• Then click the tab "Themes"
• And, for the selection input labeled "Admin console theme", select "keycloak"
• Logoff and login again

• Now, if you try to configure this provider again, keycloak should render all configuration fields and everything else should work fine.

  See issue #19 for further information.
