I'm not sure exactly what you're seeing. When I test, the behavior is working out as I'd expect:
From the EasySocial activity stream, I click the share button:
On my timeline appears:
When I click the post in the Facebook Timeline, it properly brings me to:
alcarajo.com.ar/Comunidad/Actividad/Elemento/1206.html?xhtml=1
If I debug that URL, I get an error about 2 tags for og:title. Thats a correct error because EasySocial is inserting the following tag:
<meta property="og:title" content="Santiago
actualizó su foto de perfil" />
That tag is improper because there is a carriage return. If there was no carriage return in the line, JFBConnect would properly detect it and not add our own title tag. Facebook would also have a better chance at reading it.
Either way though, Facebook seems to be scanning and reading the pages properly, so please let me know exactly how you're testing and what you're seeing.
From your description above, the main URL is being shared. The EasySocial thread discusses the image being wrong. What is the actual problem you're having. Step by step instructions and images of the issue would really help.
Thanks,
Alex
