No, I havn’t. How do I do that? FYI, I’m on the Pro (hosted) plan. So don’t have access to any source code.
Also, the documentation said:
All of our official themes support member comments by default." - source
And
Ghost Pro users can log in and start enjoying all of this right away! If you’re a developer, self-hosting Ghost, you’ll need to upgrade to the latest version to get access to everything that’s new. - source
So if I understand correctly, I should have access to the comments by default.
