I tried to sign in to JingleMad Radio, but a message popped up saying "The default role has not been configured." Can someone out there please fix the error?
This is the support community for the software that the mentioned page is using. Not the support for their service.
You need to contact them and tell them about your problem. I doubt that they are following the discussions here on this page. And even if they do, you could have chosen a more meaningful topic than "Help" which is what most of this discussions are all about since this is a support forum ;-)
But if you contact them and want to have quick access to their service, tell them to read this discussion to get hints on how to solve their problem: https://open.vanillaforums.com/discussion/37293/the-default-role-has-not-been-configured-error-on-new-user-registration
