Hi, I’m using the free theme also and I am considering buying the pro version, the only thing holding me back is I cannot get the slider section to work either.
I believe the problem is because when I go to Customization > Widgets I do not have the Home Main Content Area showing there that is referenced in the documentation.
I only have Main Sidebar Area and Footer Columns 1, 2 and 3.
I am testing this theme on a site that has only has Disable Login, WP Review, and Wufoo shortcode plugins installed, and no Jetpack.
Any ideas why the Main Content section is missing?
