Set the cache period for the plugin to refresh events displayed on your site. If you select "Day", the plugin will check for updates to your Eventbrite events once a day (new events, updated information, new participants). The advantage of using caching is that event feeds load faster, and this option also saves server resources. The downside is that changes to your Eventbrite events won't take effect immediately on your site. To immediately see changes to Eventbrite events, you can clear the cache manually from the admin bar.
