I have relisted now and it seems OK. However, I can't see the problem with the original listing. This item had been up for 10 days and when it didn't sell I relisted at a reduced price and that is when the problem showed up. How come?
I would appreciated an explanation to avoid the same problem in future.
What was confusing me is that the original listing had the same link and was live for 10 days. Only when I re-listed with the price lowered and no other changes did it flag up a problem.
Oh well, no more links in my listings then. 🙂 Thanks again
