    I was using Chrome.

    I tested Firefox and Internet Explorer and the error is:

    {"errorMsg":"Failed to retrieve data for child nodes undefined","data":{"Message":"An error has occurred.","InnerExceptions":[]},"status":500}

    Might be related but since it's happening in all browsers I'm not sure.
