HBook does not update with my iCal external calendars automatically. The sync has stopped.

🤔 Problem

• The sync is not working properly. When I receive a reservation on an external calendar, it does not import into HBook.

• HBook does not update automatically, and I have to click on "Update calendars" for the synchronization to run.

🌱 Solution

If the sync has stopped, we recommend proceeding as follows:

1. Deactivate and re-activate HBook: the wp_scheduled_event which is responsible for the synchronization is registered upon plugin activation

2. If that does not solve your issue, install WPCrontrol plugin and check that the 'hb_ical_synchronized' cron appears

3. If it appears, but it is not triggered, you should try to modify your wp-config.php file to set an alternate cron, as explained here in the codex adding in your wp-config.php :
   define( 'ALTERNATE_WP_CRON', true );

4. If the issue remains after taking the steps above, send us a support request.
