I can’t find that you answered this question already, except obliquely. I have blog content already, so I can’t use the Demo (unless you have a way to do this where I won’t lose my content). All I want is a blog. I don’t need the other stuff for now. But in setting up, under the Template section for choosing a Home Page, there is no Home Blog. There is a Home Blog option on your live demo. Where is it on the Home Page choices?
I have attached 2 screenshots so you can see it’s not on the list of Home page options:
I hope you are well today and thank you for your question.
For the Blog home page you have to set home page template to blog and then configure blog page settings as shown in the attached screenshot.
