No overview of posts when Yoast SEO is enabled

When you install the Phlox theme and Yoast SEO plugin the overview of posts is empty. The content section is white. The rest of the theme works perfectly.

In /themes/phlox/index.php you will find this code snippet row 2:

if ( have_posts() ) {
   if ( ! function_exists( 'elementor_theme_do_location' ) || ! elementor_theme_do_location( 'archive' ) ) {
     get_template_part( 'templates/theme-parts/loop', get_post_type() );
   }
}

When you activate YoastSEO the value of get_post_type() will become ‘page’. When you disable the plugin it will be ‘post’. ‘Post’ is the correct value.

I have reported this bug also on at the Yoast SEO support forum:

But maybe the theme authors must solve this. Please let me know.
