Compatibility between storefront-powerpack and YITH Multi Vendors

To make the two plugins are compatible you should add this code in the functions.php of your theme:

if( is_admin() && class_exists( 'WooCommerce' ) && function_exists( 'YITH_Vendors' ) && function_exists( 'storefront_powerpack' ) ){
    $user = wp_get_current_user();
    if( $user instanceof WP_User && ! current_user_can( 'manage_woocommerce' ) && in_array( YITH_Vendors()->get_role_name(), $user->roles ) ){
        remove_action( 'init', array( storefront_powerpack(), 'includes' ), 0 );
    }
}
