I have read several threads with (no version folder) in the title, but none of them helped me. My problem is that I made a (no version folder) mistake when I listed an item. When I try to edit the listing it returns: 'The page you were looking for doesn't exist.' (see screenshots). I tried recreating the listing from scratch, re-editing the object to a new version, properly nested in a correct version folder that returned no errors in the Check for errors dialog. When I try to list the item again using the Firestorm Marketplace Listings dialog, it lets me go through the whole process of listing but no listing is created! This is an entirely new product which I have never listed or sold, so I was unable to find the original ID for the item in error. I tried associating the replacement listing with 25873010 taken from the error URL: https://marketplace.secondlife.com/merchants/273692/store/products/25873010/edit?per_page=10 but this failed. I seem to be unable to create a new listing, or to delete the broken listing. Please help!
