NO thumbnails post at Facebook?

og:image is missing, I saw on Facebook Debugger.

Add something like this in your header.php.

<?php if (have_posts()):while(have_posts()):the_post(); endwhile; endif;?>
<!-- Facebook Opengraph -->
	<meta property="og:url" content="<?php the_permalink() ?>"/>
<?php if (is_singular()) { ?>
	<meta property="og:type" content="article" />
	<meta property="og:title" content="<?php single_post_title(''); ?> - Folk Estrada" />
	<meta property="og:description" content="<?php echo strip_tags(get_the_excerpt($post->ID)); ?> Folk Estrada" />
	<meta property="og:image" content="<?php $thumb = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'large'); echo $thumb[0]; ?>" />
<?php } else { ?>
	<meta property="og:type" content="website" />
	<meta property="og:site_name" content="Folk Estrada" />
	<meta property="og:description" content="Folk Estrada" />
	<meta property="og:image" content="<?php echo get_stylesheet_directory_uri(); ?>/images/folk-estrada.png" />
<?php } ?>

its not help me … i try find problem with https://developers.facebook.com/tools/debug

and it say ‘Error Parsing URL: Error parsing input URL, no data was scraped.’ ?

I would suggest that you use a plugin for FB such as:

https://www.ads-software.com/plugins/facebook/

Or JetPack.

I’m new to WordPress. I’m not sure if I have reached the correct place to post questions. I ran the Facebook Debugger Tool and not sure what it means. Please point me in the right direction if I have posted this question in the wrong place. Thank you.

Errors That Must Be Fixed

Meta Tags In Body Your page has meta tags in the body instead of the head. This may be because your HTML was malformed and they fell lower in the parse tree.
Please fix this in order for the tags to be usable.
