This theme routes templates to a custom folder. Therefore, get_header(), get_sidebar(), and get_footer() functions should be replaced with get_template_part('partials/header'), get_template_part('partials/sidebar'), get_template_part('partials/footer'). You can use get_header(), but it will be serving the default header file included in WordPress core.
