When you have more than one shared IP's even though you might have not configured any resellers (some like to configure shared IP's for resellers).
Actually it might look something like this:
Shared IP address for root. – IP #
Shared IP address for nobody – IP#
Truth is we only need one share IP for root, in addition in /usr/local/apache/conf/httpd.conf you might have the following lines:
# WHM DOMAIN FORWARDING VHOST
ScriptAliasMatch .* /usr/local/cpanel/cgi-sys/domainredirect.cgi
What's the cause for this ?
The answer hears to Domain Forwarding that you have enabled and there's an easy way to solve it.
Navigate to WHM -> DNS Functions -> Setup/Edit Domain Forwarding and set it to disable.
Rebuild/Restart Apache and your are ready !!
