You aren’t going to get much help when you supply that little info. We have to assume and guess about a lot of things.
can you give us more info please?
Do you want to stop items only from the calendar or delete them completely from Events Manager?
I want to keep the Events, but delete them from the calendar.
you need to assign a category to your events that you do not want to show in the calendar and then use shortcode like [events_calendar category=”-X”] where x is the events category id with – means these events with category id X should be excluded
