I've got a new multisite install with domain mapping installed. I've followed the instructions and the domain I'm trying to map goes to my site's dedicated IP address. When I attempt to map the domain with the plug in, I simply get a spinning indicator which spins forever. I've got the sunrise file in, I'm using subdomains and I have a properly functioning wildcard entry. sunrise is indeed enabled in wp-config.php.
Any assistance is greatly appreciated.
