When attempting to add a new slave, upon clicking the "Add Slave!" button, after about a minute, I get an empty page. My DNS server doesn't show any AXFR attempted. What could be the problem? I attempt to attach a screenshot here but it is not allowed.
I'm getting the same thing. Had an issue with my local DNS. Deleted and tried to re-add, but now my domain is down.
I've already contacted support, now waiting for a response.
It worked today. Maybe something changed on the backend, or maybe some cached data expired that was leading to the blank page state.
