Facebook sharing problem - Meta URL by Marco D'Ascenzo

Hi guys,

I tried a lot of hack to make the sharing button working correctly, but it doesn't work when I try to share any pages on Facebook. 
Already looked here https://ecommerce.shopify.com/c/shopify-discussion/t/facebook-og-image-grabbing-incorrect-product-image-thumbnail-161040 but still... doesn't seems to fix my issue. 

URL is not found even when I use the Debug tool from Facebook. 
http://www.bonbon-conceptstore.com/collections/jouets-1/products/pebble-large-animal-tigre-200-010tig

Last code I use is this one

{% if template == 'product' %}<meta property="og:type" content="product "/><meta property="og:url" content="{{ shop.url }}{{ product.url }}" /><meta property="og:image" content="{{ product.featured_image | product_img_url: 'original' | replace: '//cdn', 'http://cdn'}}&quot;;; />             <meta property="og:title" content="{{ product.title | escape }}" /><meta property="og:description" content="{{ product.description | strip_html | escape }}" />
 {% endif %}

Need help here. 

Thanks!
