Event Rocket is a set of hacks and utilities that add some extra capabilities to <a href="https://wordpress.org/plugins/the-events-calendar/" rel="ugc">The Events Calendar</a> and <a href="http://tri.be/shop/wordpress-events-calendar-pro/" rel="nofollow ugc">Events Calendar PRO</a>. It is no longer supported and is unlikely to receive further fixes. Don’t be fooled by the Last Updated field that displays on the WordPress.org plugin page … it does not reflect the true status of this plugin.
