You have a shortcode generator icon in the page editor which have a shortcode for calendar with several options like event preview, category filter. You can insert the calendar from there or can use this shortcode: [event_calendar category_id="" filter="" preview=""]
I have been using the Gaea theme for about 2 years. In the past, when I created an “event” it would appear in my calendar. Recently, the information has stopped flowing to the calendar. There is now NO information in the calendar. Help?
