I went directly to Ebay's website and tried a listing that failed when scheduled through Auctiva.I immediately got a reject notice that the listing wasn't allowed because I offered to accept a payment form not permitted by Ebay.Then they show a link to their policies on how you can accept payment.Here is link if interested.Wish there were some way that Auctiva could give that detailed information for reason for rejected listings.
