Hello. I tried to find a solution for my problem, but without success.
When I sharing k2 items on Facebook, in source I see that source of og:image is webiste but duplicate.
For e.g.: http://www.site.comhttp://www.site.com.
I use Social Connect for social login and for Facebook comment. I use Gavick template (I also ask them, they don't have a solution for me). I use Joomla 3.3.6.
Because of that, Facebook doesn't see my pictures. I set in k2 parameters size for image XLarge, and in category options I set item view image large.
My items wrote on Cyrillic (sr_RS) and Facebook see it like this:
"description": "\u0420\u0435\u043a\u043b\u0438 \u0431\u0438\u0441\u043c\u043e....",
Like you see, weird characters.
fb:admins and fb:app_id tags are missing. These tags are necessary for Facebook to render a News Feed story that generates a high click-through rate. (I don't know how to set it, I wrote it in template options).
og:image was not defined, could not be downloaded or was not big enough. Please define a chosen image using the og:image metatag, and use an image that's at least 200x200px and is accessible from Facebook.
Please, help me!
