Hello Geoff,
first of all, thanks for your help. Maybe I'm a little late, maybe my english isn't good enough.
But the help says:
... that is actually exactly what I want. If someone type in ypsyps.co.cc he should see the ypsyps.heliohost.org content.
Now I have removed the parked domain, and did the addon domain instead (as you suggested to do).
Now I have a subfolder (ypsyps.co.cc) in my public html folder, but the domain still dosn't work.
If I type in the full url "ypsyps.co.cc/index.htm" it works fine.
But schould not work "ypsyps.co.cc" too? Instead I will redirected to "ypsyps.co.cc/cgi-sys/defaultwebpage.cgi".
The same situation as with the parked domain.
