Breadcrumbs

Put the following in your child theme’s functions.php file.

add_filter( 'woocommerce_breadcrumb_defaults', 'edit_wc_breadcrumb' );

function edit_wc_breadcrumb( $args ) {
     $args['home'] = '';

     return $args;
}

So there is nothing wrong with that code. Double check you copy and pasted it correctly. Perhaps post an screen capture of where you pasted it. You can link the screen capture here.
