If you have regular events configured within your BookingBug account, it is possible to cancel just a single occurrence of the event using the following steps.
Use the calendar on the left-hand side of the dashboard to click the date of the event you wish to cancel.
Click Details on the right-hand side of the event.
In the bottom left corner, the details pop-up will appear and click Actions.
Click Cancel This Date.
If you would like to send a cancellation confirmation email click, Yes, Please E-mail, if a cancellation confirmation email is not necessary, click, No, Just Delete.
This will then remove the regular event from occurring on the date specified, without amending any other occurrences of the regular event.
