Have reviewed your install. Not sure what's going on, but the cbrvs cookie isn't being created which is used by the spoof checking. Only solution I can see at this time is to toggle off spoof checking entirely within CB > Configuration > Integrations, but that would ideally just be a temporary fix. I'm not sure what's causing the cookie to fail to create. Other cookies appear to be working fine. You may want to check with your host to review error logs to see if setcookie is failing possibly due to some sort of security implementation.
