On a Cpanel server, website is working fine. But it is not shown in WHM.
I have checked cpanel users folder at
/var/cpanel/users
I found a file with user name of the domain “netfor” exists there.
I have checked it content. It was
# cd /var/cpanel/users
# cat netfor
IP=65.75.183.50
STARTDATE=1106613195
RS=x2
OWNER=root
PLAN=Personal
MAXPARK=unlimited
MAXADDON=unlimited
FEATURELIST=default
XDNS1=netforhost.com
It seems the problem is because the web site was parked in one of the domain or DNS clustered with this server before it moved from another server.
So i modified the content of the file /var/cpanel/users/netfor as below
IP=65.75.183.50
STARTDATE=1106613195
DNS=netforhost.com
RS=x2
OWNER=root
PLAN=Basic50
MAXPARK=unlimited
MAXADDON=unlimited
FEATURELIST=default
Now it start showing on WHM and able to upgrade or downgrade as required.
