@ptwdirect1987 Do you have a module which is overriding following class.

 Mage_Page_Block_Html_Head

or check core file app\code\core\Mage\Page\Block\Html\Head.php for any modification.

I think addEMItem should be addItem.

[ptwdirect1987]

hi there when seraching for addEMitem its not showing up all it hass is additem what would you suggest maybe adding addEMitem
