The listing closed this morning so definitely not past the 45 days. After a few clicks around and getting the blank screen, it suddenly popped up with my listing and I could re-list. However, trying to add a new motorcycle still brings up the blank screen.
When trying to relist an unsold motorcycle, I just end up at a blank screen, nothing else. The same happens regardless if I use the website with Chrome or Firefox, or Android App. I even tried to just start a new listing, then I get the same blank page.
