I can't upgrade the site plan so i can use a custom domain

Hey everyone,

I want to upgrade my site plan from Starter to Basic so I can add a custom domain, but I don’t understand why the option is not clickable so I can upgrade (and pay!).

Where should I go to do so? I’m on “Dashboard” > “Plans&Billing”

Thank you!
Susana

Your site likely has CMS items. You can’t use starter if you are using the CMS
