What a problem?

you have adns problem. namely “nameserver loop detected” according to http://www.squish.net/dnscheck/

You need to look into your dns settings or per haps the data hasn’t propagated yet and you just need to wait a while (unlikely though).

Looks like your DNS is messed up a bit.

;; AUTHORITY SECTION:
webmlmresponder.com.    10800   IN      SOA     dns1.hu. hostmaster.dns1.hu. 2010012501 86400 7200 3600000 3600

Check your BIND settings as the below is what you have set for Authority on your TLD.

;; AUTHORITY SECTION:
webmlmresponder.com.    172799  IN      NS      dns1.hu.
webmlmresponder.com.    172799  IN      NS      dns2.hu.
webmlmresponder.com.    172799  IN      NS      dns3.hu.

Thanks this info… I probe revision and setting…
