My shortcodes don’t work now

With the last update my shortcodes not work fine:

// INTéGRER LES éTOILES YOPTO VIA CODE COURT
function wycan_yotpo_stars_single( $atts ) {
if ( function_exists( ‘wc_yotpo_show_buttomline’ ) )
{ add_action( ‘woocommerce_single_product_summary’, ‘wc_yotpo_show_buttomline’, 15 ); }
}
add_shortcode( ‘wycan_yotpo_stars_rating’, ‘wc_yotpo_show_buttomline’);

// INTéGRER LES AVIS YOPTO VIA CODE COURT
// Add the reviews area inside a single product template with elementor, simply add the shortcode widget with [wycan_yotpo_reviews_rating]//
function wycan_yotpo_reviews_single( $atts ) {
if ( function_exists( ‘wc_yotpo_show_widget’ ) ){
add_action( ‘woocommerce_after_single_product’, ‘wc_yotpo_show_widget’, 15 ); }
}
add_shortcode( ‘wycan_yotpo_reviews_rating’, ‘wc_yotpo_show_widget’);
