Best Offer - access to checkbox

I can’t activate either the Best Offer checkbox or the magnifying glass

Are there other setting that have to be configured in a specific way to get this to work?

Hi, the selected category might not support the BO option.
Also, the BO option is only supported by fixed-price items (Buy It Now) so if you have “Starting Bid” selected you should unselect it.
