can you help me?
i need to change a NameServers!

I did a whois lookup for your domain and it seems that your changes didn’t go through at all. It says you haven’t updated the whoise since the 15th of july.

I’d try and put the changes through again today, and then go back into the panel 20 min later and see if that shows the new name servers. If the update still isn’t sticking for whatever reason you’ll need to contact support.
