Wrong facebook thumbnail (on like & share)

Guys, I really need a hand here. I’m posting this for the 100th time i think, and no one could fix it ?? Everything worked perfect, until I updated my wordpress version to the latest one.

I’m having this problem for over a month now, and it’s “killing” my visitors.

Please check my site, and suggest me something. I’ve tried almost every plugin for this issue, but none worked.

Please also check the Facebook Lint too, it may help.
