Hm, i accidentally updated your another site to Easysocial latest version, is it okay for you?
By the way, regarding with your current site issue, I already tested on your site with latest Easysocial version, it seems the issue still persists and I can replicate this issue on my locally site, I will create a ticket in our issue tracker and will include the fix in next release version.
For now you have to download my attached file and replace into JoomlaFolder/media/com_easysocial/apps/user/shares/helpers/stream.php
