Trying to list, keep getting "null" notice

[eastlanddesigns1]

I'm new to ebay. I have a few items listed for sale, haven't had a problem listing anything until now. I'm trying to relish an item because previous buyer turned out to be a scam. Now when I try to relist I keep getting an error notice saying I to edit null. The same type of notice you would get if you forgot to add a category or description, but it just says null? Does anyone know how to fix this? I have already tried to re do the ad, but still get the same message. Help!
