When I open an incognito window, I don't get the error, I guess because it doesn't view me as being logged in as admin.
But people will still have to enter an email address and name to comment as guest. I think I'll leave it that way.

Try adding to Design > Custom CSS
.squarespace-comments .comments-content.read-only .new-comment-area { display: block; }
