How do I set my own domain to be the primary domain?

[nauticca90]

Also I don't see in your cPanel an option to manage different domains or being able to create different FTP accounts for the different domains.
I tried several times making my own domain be the main one: www.blogn.net, but I keep getting errors, I would appreciate it if you can set it for me.
Thank you!

You should be able to modify your main domain by following these steps:
1. Login to your account information panel.
2. In the navigation bar, go to Hosting => Modify Domain.
3. Fill in the form accordingly, and click the submit button. This could take a few hours to process.

but I keep getting errors

What error?
