[shamsat]

Hi,
I added the one A record for example "example.net" and want to add the second A record "www.example.net" but i get the error:

Unable to fetch the domain name: example.net from zoneid 158101

as well cannot add the second MX record and get the above error?

Try creating a cname for www and pointing it at @

I have a funny feeling your trying to actually use example.net ??  You need to use your own domain ;)

And then you would want to create AAAA records would you not - your doing the cert test?
