No images or videos from wordpress to facebook walls

This is my new website.

https://voluntaryvirtues.com

Can’t seem to figure out why I can’t get my wordpress post’s videos and images to load/show on any facebook walls. When I copy and paste the various website’s urls (pages, posts, front page), it just gives me some plain boring url text and no description even. Any help would be greatly appreciated! I can also give you a list of my plugins, maybe one of them is creating a glitch.

Thank you for your time. I really, really do appreciate it.
