How do I reopen online bidding?
For online items there are two steps:
- change the online bidding close time (otherwise they would close immediately again) ... click on Website -> Online Bidding
- to reopen all items click on Items -> Open/Close Bidding -> Open All Items (or Open unsold items for those without bids only)
If you want to open individual items there is a button to open or close the bidding on the left of the item details page.
