I am using plesk control panel and using zoneedit. All my websites are configured correctly when I set up those. My problem is some of my websites are are diverted to other websites without my knowledge. eg: http://www.mydomain.co
and http://mydomain.com worked correctly when I setup the websites. Now http://www.mydomain.com is working correctly. When I type http://mydomain.com it is going to a different website.
How can I solve this problem
