Ping request could not find host forumi.eu.org. Please check the name and try again.
For starters, you'll need to set the A record for forumi.eu.org to something such as 198.91.81.# . Check your Shared IP Address in cPanel.
That domain is not even hosted here (or at least not under the account you post from), the domain needs to be added in control panel as either parked (alias of the main domain) or as an addon domain (separate site).
In order to be able to add the domain you need to set the domain to use our nameservers, they are ns1.x10hosting.com and ns2.x10hosing.com
Please note that the domain can not have any other nameservers listed for the domain to work properly.
