You have cloned your event or are updating your schedule and would like to remove more than one speaker at a time.
1. Head to your Event Organiser Dashboard and click on the Content option from the left-hand menu.
2. Click the Speakers option, and you will now see the list of all your Speakers.
3. If you'd like to delete more than one Speaker, tick the box next to their name to select these and click on Delete Selected.
4. To remove all your Speakers from your event, select the Delete All option. (... > Delete All)
Once a Speaker has been deleted, it can't be undone so you will have to manually enter their information into your event again.
Deleting a Speaker that has a Talk associated with their record would make that Talk record not viewable on the front-end site. Always remember to first cancel any sessions associated with any Speakers (that you'd like to delete) to ensure all info is correctly accounted for.
