[Theme Horse Support Team]

just read this blog to unhook the function
http://wordpress.org/support/topic/how-to-remove-an-action-via-functionsphp-in-a-child-theme.
Hope this helps you. You can fix it by making child theme and under child theme make functions.php file
and first unhook it and remove the tag which you don’t want or you may even hire developer to fix it.
