ERROR: This product is currently unavailable.

This message appears when a buyer attempts to order an item with an Item Expiration date that has passed. To allow buyers to order the affected item again, go to Manage Products > Edit/Clone Products, select the affected product and click View/Edit Product. Make sure the box Show advanced settings is ticked, and scroll down to the Inventory Control section where you will find an Item Expiration date setting. You can simply delete the date and leave it blank to remove the expiration entirely, or change the date to a future time when you want the item to become unavailable again, then click Submit to apply changes.
