today I’ve got the error “Invalid Action Token (Code: 9303)” on the DNS Service Cloudflare.com whenever I tried to add a domain after the registration.
The Solution to this is very simple.
So just make sure your browser isn’t blocking the referrer or add Cloudflare to the whitelist if you’re also using a plugin like Referrer Control on your webbrowser.
Don’t forget to reload Cloudflare after re-enabling the referrers.
Simple as that!
