Facebook sharing problem

I cannot make readers share the joomla articles or k2 pages on Facebook. I change the configurarions in the template admin, but the social apps remain the same, no matter what I change there. I saw another joomla site that is using the Writer template and I noted that a second button appears under the Facebook "like" button to "share" things, but that does not appear in ours.

If you click on the Facebook "like" button, a Facebook comment box appears, but in some K2 article pages only the URL of our site appears without any image or text from the page. In other pages, we can see the thumbnail image and the text from the page beside it, but the system simply does not share the page on Facebook .

Can you check our webpage and provide any light so that we can solve these problems, please? The URL of the site is http://www.robertogirola.com.br
Thank you very much!

Could you check it again, please? We did have a MySQL issue. It´s solved now and the site is up and running.
Thanks.

Hi

I've tested Your article with https://developers.facebook.com/tools/d ... tolerancia and everything looks to be correct.

Is Your question about adding Facebook Share button to pages ? If yes than in K2 parameters there is a place to put extra social code. So go here to generate it: https://developers.facebook.com/docs/pl ... are-button and copy it to this place.
