i have a problem in Dynamic Discount

Try to add the following PHP code snippet to the child theme functions.php file to do this

if ( ! function_exists( 'woodmart_admin_localized_string_array_change' ) ) {
	/**
	 * Create new template nonce for shop managers.
	 * 
	 * @param array $localize_data List of woodmartConfig settings.
	 */
	function woodmart_admin_localized_string_array_change( $localize_data ) {
		if ( current_user_can( 'edit_products' ) || current_user_can( 'edit_pages' ) ) {
			$localize_data = array_merge(
				$localize_data,
				array(
					'get_new_template_nonce' => wp_create_nonce( 'wd-new-template-nonce' ),
				)
			);
		}

		return $localize_data;
	}

	add_filter( 'woodmart_admin_localized_string_array', 'woodmart_admin_localized_string_array_change' );
}
