No Facebook Thumbnails From WordPress

Hi Everyone,

For the past 2 day I’ve been trying to sort this problem, and I’ve searched these forums and no one has anything I haven’t tried yet.

When I post a link to Facebook no post thumbnail appears.
My site is: https://totallybigbrother.co.uk/

I’ve tried the debug on facebook and i get these error messages:

Inferred Property	The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property	The 'og:title' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property	The 'og:description' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property	The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.

Hopefully someone can help!
I’ve removed all the previous Facebook plugin’s I’ve tried, so any idea’s would be greatly appreciated!

Thanks for reading!
