ok so…
installed jQuery updater…nothing happened
installed jQuery migrate as recommended from the jQuery sit before messing with the version number.
It looks like the designer created files to override the jigoshop files.
the only reference to the version of jQuery was this line in a file called jigoshop-functions.php (jigoshop/jigoshop-functions.php) found within the theme template files.
include_once('shortcodes/cart.php');
add_shortcode('my_cart' , 'get_my_cart');
if (!is_admin()) {
wp_enqueue_script( 'jquery_ui', get_bloginfo('template_url').'/jigoshop/jquery-ui-1.11.4.custom.js', array('jquery'));
wp_enqueue_script('jigoscript', get_bloginfo('template_url').'/jigoshop/jigoscript.js', array('jquery'), '1.0');
wp_enqueue_script( 'jigoshop_script', get_bloginfo('template_url').'/jigoshop/script.js', array('jquery'));
}
I entered a more updated jQuery version there but still nothing.
