Is this possible? I just changed the server of my site to my own nameservers, and now I get the cPanel "There is no website configured at this address" error. Is it possible to customize or change this page?

Thanks in advance

If you are sure that it is not DNS isssue then check in your webserver for this site. May be config problem or missing

That file is located at /usr/local/cpanel/htdocs/index.html
