If you have set up your custom domain on Kajabi using the Create subdomain for Kajabi site option, and chose to connect a subdomain with www in the URL, you'll likely want to set up a forwarding rule through your domain registrar to redirect the URL without www to the same site.
Set up a URL redirect on Bluehost
Note: The redirect process described in this guide only applies if you've connected your custom domain using the Create subdomain for Kajabi site option in your Domain Settings. If you've connected your domain using the Connect domain to Kajabi option, there is no need to set up a forwarding rule.
First, check that your domain is set up properly in Kajabi:
From the Kajabi Dashbord, open the Settings tab.
Under Site settings, click Domain.
Confirm that the custom domain is connected.
Log into your Bluehost account and navigate to cPanel.
Open Domains.
Click Redirects.
Fill out the Add Redirect fields.
Select Permanent 301 and then choose the correct domain in the dropdown menu.
Under Redirects to → type in
