Hi no, there are two dissapearing acts :-
1) when you first join Auctiva, all your listings are pulled off line by eBay when eBay checks that your account has not been hijacked. That is what I am referring to at the start of this thread.
2) During maintenance (the effective day & time varies depending on where you are in the world)
your images do not appear in your scrolling gallery or Auctiva store, this happens once a week. Your listngs stay live on eBay.
