Changing the document root for a primary domain name
On our cPanel hosting services, the primary domain name’s directory will always be public_html/ and this cannot be changed in the Domains section of cPanel (like how you can change this for add-on domains and sub-domains). However, you can add the following code to your site’s .htaccess file to nominate a different folder for your site to load from. PLEASE NOTE: This method is for advanced users and is not recommended if you are not familiar with modifying your website’s .htaccess file.
In this example, change “yourdomaingoeshere.com” to your website’s domain name, and “nominatedfoldername” to your website’s nominated document root path.
