Hello, I can not reply to your message on this post : https://www.howtoforge.com/community/threads/sub-domain-as-website-domain.85794/ About the trailing, there no just this demo.clicshopping.org About the 2ns I put this ip : 213.186.33.199 maybe is this ? 94.23.7.166 or ns320556.ip-94-23-7.eu no ? thank you
change the 2nd ns record to NS320556.IP-94-23-7.EU. and then recreate the dns zone on that nameserver, or properly configure it as a slave of ns.kimsufi.com
for the demo.clicshopping.org A record, if there really is no trailing . it will append the domain name and resolve as demo.clicshopping.org.clicshopping.org. i would suggest just changing it to demo so that it matches with the mail and www subdomain syntax.
