You can configure add-on domains for their folder paths with no problem within the cPanel. However, the PRIMARY domain - the domain you specified when you purchased the hosting account, will need to be set by our systems team. They have to do what's called a document root change. You rneed to submit a request to firstname.lastname@example.org for the change to be made. Additionally, make sure to send the email, or contact our live support team.
I have added a addon domain but still not working.
New Domain Name: folder1.com
Document Root: public_html/folder1
Do I need to do anymore? Change DNS or nameserver configuration?
