I've made some custom meta boxes, but I can't get the info to display outside the loop.
I've tried using this but I get nothing

global $post;
$args = array('post_type' =>'post-type');
$meta = get_post_meta($post->ID, 'meta-box-slug', true); 
wp_reset_query();

And I've tried this too

global $post;
$args = array('post_type' => 'post-type');
$obituary_query = new WP_Query($args);
while ($obituary_query->have_posts()) : $obituary_query->the_post();
$meta = get_post_meta($post->ID,  'meta-box-slug', true); 
echo $meta;
endwhile;
wp_reset_query();

That does displays the data but it throws a "Headers already sent error"

I'm not sure what I'm doing wrong. I haven't had much luck working with custom meta boxes.

Thanks in advance.
