Finally had time to get back to this - I shut the station down for maybe 30 seconds and restarted. It still comes up as 'chrisjonesmedia.com'. Did I miss a setting somewhere?
We can see this has been updated fine in the control panel but it looks as though you will need to also update this in your Shoutcast Authhash settings. You will need to log via the 'Admin' area of your control panel and then make the necessary changes to your Authhash.
Thanks for the link - I followed the instructions - the shoutcast site has the URL correct, but I am still seeing chrisjonesmedia.com in the Internet-Radio pages.. Baffled. I am missing something..
