The issue is that the voucher type has expired.
- In the Booking Engine, go to Vouchers → Vouchers (middle option)
- Select the voucher that is no longer available and select Edit in Actions
- Check the Valid From & Valid To dates approx halfway down the page:
- Extend the Valid to Date for as long as you want this voucher to be available.
NOTE: the Booking Engine sends an automatic email a few days before the voucher type expires to the main email address associated with the Booking Engine i.e. usually info@ or reservations@
Please check your junk mail and ensure that these emails are arriving in your inbox and that they are being actioned when received.
