open-graph

Good night I have the tags on my site for sharing on facebook <meta name='og:title' content='Desapego Games - Troca, Com ... on my page. Could anyone help me fix this ? I've tried everything I copied the code of sites that work and does not solve.

Dear, Facebook does not show the page image automatically. For the image to appear, I have to go to the Facebook "Share Debug ... contains a loop."I imagine it is because it has 2 versions. I've been breaking my head for quite a while. I appreciate help.
