I have a question and need someone kind to help me, thanks: It is about the problem in posting listings, when I'm in the page of saved listing, I put a check mark next to one listing, then click the "Post Now" button above, in this case, there will appear some words like this "The following 1 listing(s) were unable to post because they did not pass validation and need to be edited before posting" and couldn't be posted. However, if I use another method: click the link of this listing and come into the page of creating, then click the button "Post" at the bottom, it will be successfully posted. Is anyone could tell me why this situation occured, and what is the difference between this two methods. A response will be very appreciated, thanks.
