If there are buyers getting errors when trying to purchase, it could mean that some or all of the tickets on the offer have been invalidated by some kind of adjustment on the provider side (dropped from the account, sold, repriced, etc.). If this is the case, the best way to ensure that all inventory on the offer is valid is to delete the tickets and reimport them. Below you will find the steps to do this.
Go to the Tickets tab on the Offer (backend)
Click the "All" checkbox at the top of the list of inventory to select all tickets
Click the "Delete Tickets" button above the list of inventory
In your ticketing provider system, remove the tickets from the reservation/hold
Put them back on a new reservation/hold
In FEVO Enterprise, use the new reservation/hold information to reimport the tickets onto the Offer
