domain masking problem - help

[dunff3]

Ok so I uninstalled WordPress and in makes no difference.

EDITED:

Question:

I have mydomain.com set up with the x10 nameservers and registered as a parked domain. When I visit mydomain.com it redirects to mysite.x10hosting.com and the address bar changes. No scripts are installed on my x10 account.

How do I mask the URL and make it so that mydomain.com is shown as the URL e.g. visiting mydomain.com/page.html would load mysite.x10hosting.com/page.html but not change in the address bar?

Thanks
Edit:
For a moment I thought it was fixed (has anybody changed any settings?) but since re-installing WordPress the problem has come back. How do I keep mydomain.com in the address bar and have all directories relative to mydomain.com e.g. visiting mydomain.com/page.html would load mysite.x10hosting.com/page.html but not change in the address bar?

Nameservers should set to ns1.x10hosting.com and ns2.x10hosting.com, Once they are changed, login to www.x10hosting.com/login and find the "Account Details" section, check the box to use your own domain and enter it there. Or, you can "Park" it in the cPanel section of your website to keep your existing domain as your main one.

in your parked domain do you have it redirected to your sub domain?
are you html links to relative paths? or are they to your subdomain/path?
