Hi, K2 is a fantastic component that rarely gives problems and I've been using it for 9 years. But now I have an issue in the new version 2.10.3, where Facebook posts don't load the images, actually get swapped images from other stories.
No problem in Jooma or Template Helix 3, and even installing the VM OG Meta Tag plugin, debugging on Facebook, the error of the images continued.
The solution was to return the K2 version to 2.10.0, solving the Facebook post image problem.
Could you help me understand what happens in this version? Or any settings or changes needed?

Thanks.

Turn on RSS Channel, check again on demo site.
No check only code try to share.
IN my site RSS is causing problems

It's strange, on my Facebook account the posts are correct, images, titles, text. On the site's client, posts sometimes don't carry the correct image, sometimes they change the article title for another title, all very strange.
This Joomla with Facebook is a mess, something that never happened using Wordpress.

Note: The JoomGallery component no longer loads images on Facebook, it takes an advertisement. And even with several OpenGraph plugins nothing solves.

I write, you should test OG TAGS with RSS feeds enabled in K2.
In code html looks good but if you try share via facebook Image is not from this article and titile. Although the og tag looks correct in the code.

Hi, sorry for the delay in replying. The problem has stopped and is now working fine and I'm not even sure why it fixed it, but everything is ok.
Another problem appeared on the client, where it creates an article and Saves. Then when opening the article again to edit and save, it gives a 403 error.
Strange what happens on his PC and Smartphone, but on my equipment it doesn't. Then install the version that indicated Development Release.
Maybe there is a plugin interfering yes, it will only be very difficult to know if it is from third parties or Joomla. Thank you very much for the help.

Open graph does not fetch the image correctly from the text editor. Some new option has been changed and in the new K2 2.11.0 versions the Phoca Open Graph Content plugin downloads the image from the previous article. Without this plugin, open graph did not work on facebook. The image appears first in the text editor. I don't use adding pictures in K2. As of K2 2.10.3 open graph works fine with phoca but has a conflict with joomla gallery.
