Hey Kurl,
I am sorry for the delay of this reply,
I've tried to access in your Joomla backend, but it keep redirect to your homepage.
By the way, I noticed you have enabled lockdown mode in Easysocial settings, if you enable this, Facebook unable to crawl all of your Easysocial stream content/image, because they do not have login access in your site.
To fix this, you have to
disable "Lockdown mode" from backend > Easysocial > settings > general .
Then go to Facebook debugger tool ->
https://developers.facebook.com/tools/debug/ clear your stream URL cache.
e.g. check my second and third screenshot below.
Hope this help.
