I just had a message on my ebay page suggesting I change the category for one of my items. No, I wasn't going to change it, the suggested category had nothing to do with what I was listing. Anyway, I said no don't change and clicked enter and this is the message that I was shown: "You have removed all your listings and no longer have any listings to work with."
I do still have all my listings but not sure if my heart is still beating properly!
BTW, I can only view my items on .com as well, .ca seems to be down.
