This would be my site.
When I post an article on Facebook with a server uploaded image, it loads just the header as thumb picture.
I installed 'Facebook OGP, and still does not load default image.
I installed also Wordfence and found out that FacebookExternalHit (some sort of browser they use) produce lots of 404 for uploaded pictures from these articles.
It may be something with the .htaccess
Is there anyone who had the same problem, or could provide any clue ?
Thank you !
