Set Websockets Profile with strict updates

Hi I'm SteveBy5 and new here.

I've been asked to enable websockets.  I am able to set the "websockets profile" in the config page for the VS but when I update it I get the error 

010715bc "The application service (%s) has strict updates enabled, the object (%s) must be updated using an application management interface."

I assume this means I should update it in the iApp but I can't see where to do that.  Do I have to modify the template?  

Thanks in advance
