This video explains why your domain might not be working with your HighLevel funnels/websites, memberships or as your whitelabel domain.
You need a different domain / subdomain for each of the following:
- Funnels & Websites
- Whitelabeling your agency
Please Note: If you want a funnel step / website page to open without any path (domain.com instead of domain.com/home), you can select that page as the default page for that domain. A default page can be selected from Settings > Domains > Edit Domain
