How to disable cart-fragments.min.js?ver=2.0.20?

Put this in your theme’s functions.php file.

wp_dequeue_script( 'wc-cart-fragments' );

Well you need to put it into an action and put it inside your theme’s functions.php file like this.

add_action( ‘wp_print_scripts’, ‘de_script’, 100 );

function de_script() {
    wp_dequeue_script( 'wc-cart-fragments' );

    return true;
}

Actually the quotes are not correct from copying and pasting. Try this:

add_action( 'wp_print_scripts', 'de_script', 100 );

function de_script() {
    wp_dequeue_script( 'wc-cart-fragments' );

    return true;
}

I’ve tested this and it works.
