FAQ

Support is primarily available on Kieran O’Shea’s forum.
A wealth of questions and answers are available here along with a copy of this FAQ. The support forum is located away from WordPress because
at the time the original plugin was authored, the WordPress support forums didn’t provide an easy way to be notified of posts and manage things.
Recently things have changed in this regard and so the WordPress support forums for Calendar are also monitored from time to time.

This is because you need to ensure they are visible in your theme first.

To do this under WordPress 2.8 there are a pair of widgets that you can add to your side bar in the admin panel. Position them how you want.

Under WordPress 2.0 or where your theme does not support widgets you need to modify the sidebar.php file of your theme to include the following code as appropriate:

<?php echo calendar_todays_events(); ?> <?php echo calendar_upcoming_events(); ?>
