Facebook share issues [no Image or wrong one]

Hello guys! I’m facing an issue every day I try to shake my single post to facebook profile or facebook page.

I’m using the https://developers.facebook.com/tools/debug/og/object/ sometimes when I set to post to a determinated time and not now (major issue in does cases).

Sometimes it brings and old image, sometimes the same one (for some reason and I don’t define one), or non image.

My website is http://renderasnews.com/ and an example is this post: http://renderasnews.com/brewie-una-maquina-automatica-para-elaborar-cerveza-casera/

The scraper look: https://developers.facebook.com/tools/debug/og/echo?q=http%3A%2F%2Frenderasnews.com%2Fbrewie-una-maquina-automatica-para-elaborar-cerveza-casera%2F

Every day something different happen… and the way it shows it.

Now I’m using Jetpack share and “Social Network Auto Poster” (Next Scripts) but even with manual input in my Page or Profile I have the issue.

Is there any fix to this? og:image and og:description are the ones with issues.

Thanks in advance!
