ok now can enter in my web, but now for add my domain i have this error:

Error from park wrapper: todotutorialesweb.com is already configured.

why?

Please remove todotutorialesweb.com from any addon or parked domains. Then try to change your main domain again.

the problem is that not this marked in add o parking, i think the problem is because i change the main domain for todotutorialesweb.com but open other page http://todotutorialesweb.com/cgi-sys/defaultwebpage.cgi after change to the subdomain, now the subdomain work good, but when i want add the domain appear this error, what is the problem?
