Peter,
We've been testing and it turned out to be a very hard issue to understand and recreate. The issue only affects K2, which was hard to discover at first. Normal Joomla articles aren't affected. We think we finally found a good solution, and hopefully you can test it out and let us know if it helps.
Can you please edit the /plugins/content/jfbccontent/jfbccontent.php file. Around line 170, you'll see the following line of code:
SCArticleContent::addTextToArticle($article, $graphTag, "1"); //0=None, 1=Top, 2=Bottom, 3=Both
Change that "1" at the end to "2", so it looks like:
SCArticleContent::addTextToArticle($article, $graphTag, "2"); //0=None, 1=Top, 2=Bottom, 3=Both
There's another line around 185 that looks almost the same that requires the same change.
After you make the change, you'll need to use the
Facebook URL Debug Tool
to re-scan the page(s) from your site with the issue. Using the Debug Tool will show you what Facebook sees and also update their cache to make sure the old, wrong values, aren't used.
Please let us know if that helps fix your situation. We'll be putting this change into the next release of JFBConnect as it helps correct a separate issue as well, but would love to hear your feedback to know if it fixes this as well!
Thanks,
Alex
