Single pdf view post id problem?

Thanks.

It might be that this is related to my configuration only (intranet development site; Kadence child theme).

I fixed the problem in my child theme’s functions.php:

function pdfev_fixed_shortcode($atts) {
    $atts = shortcode_atts(
        array(
            'id' => '',
        ),
        $atts,
        'pdfev_fixed_viewer'
    );

    $post_id = intval($atts['id']);
    if ($post_id <= 0) {
        return '';
    }

    ob_start();

    // Set global $post so get_the_ID() works
    global $post;
    $original_post = $post;
    $post = get_post($post_id);
    setup_postdata($post);

    // Call original rendering logic
    if (class_exists('PDFEV_Functions')) {
        PDFEV_Functions::shortcode_view($post_id);
    }

    // Restore global $post
    $post = $original_post;
    wp_reset_postdata();

    return ob_get_clean();
}
add_shortcode('pdfev_fixed_viewer', 'pdfev_fixed_shortcode');
