[BUGS] Notice: Undefined index: core | It uses too much memory in Firefox

Hi,
There are two issues and I would like to report them.

First
There is a notice on the dashboard (front-end).
Notice: Undefined index: core in D:\xampp\htdocs\userideas\administrator\components\com_easysocial\includes\privacy\privacy.php on line 397

Second
Easy Social uses too much memory in Firefox 45.0.2.

Best regards,
Todor
