I'm using the Responsive theme by theme ID. Everything in the theme options > home page area is greyed out, as if I don't have permission. I am the only user on the site and I have administrator level access. I've seen a lot of different posts in regards to editing this section, but none mention every field on the home page section being unmodifiable.
I am using a child theme as well. Never encountered this type of permissions issue with any other themes.
