Calendar does not work anymore …

PHP Fatal error: Cannot use isset() on the result of an expression (you can use "null !== expression" instead) in /html/wp-content/plugins/woocommerce-appointments/includes/admin/class-wc-appointments-admin-calendar.php on line 213" while reading response header from upstream, client: XXXXX, server: XXXX, request: "GET /wp-admin/edit.php?post_type=wc_appointment&page=appointment_calendar&view=day&tab=calendar&filter_appointments&calendar_day=2016-04-23 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "XXXXX"
