Support › Meta Box Builder › Where to fill in license?
I've just installed Meta Box Builder on a new domain, and I don't see the option to enter the license.
After activating Meta Box and an MB extension, please go to the admin area > Meta Box > License, to active the license key on your site. Please read more on the documentation https://docs.metabox.io/updates/
take a look at my post, maybe it's the same, 4 days wating here...
