Calendar not updating? Check here first!

For most sites, ICS Calendar’s built-in caching will update the calendar once per hour. You can change that frequency using the reload parameter:

If you are using a caching plugin, you may find that the calendar still doesn’t update, even if you turn off ICS Calendar’s caching completely. Version 10.3.0 introduces a solution: the ajax parameter:

Add ajax="true" to your shortcode to have ICS Calendar load the calendar into the page dynamically after the page renders. This should resolve any conflicts with caching plugins. It may also help improve overall page loading performance if your calendar contains a large number of events.

The calendar functions the same once it is loaded, either way. For this reason, I do not recommend using the ajax parameter unless you are having one of the two problems described above.
