It's not really an issue but it's just nice not to see any PhP Warnings:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /public_html/administrator/components/com_easysocial/includes/parser/helpers/joomla30.php on line 62

Here's what I did, I uninstall EasySocial Beta and deleted the Tables manually to start fresh from the full package v1.0. After installing and going to EasySocial, I got that PhP Warning.

Thanks!
