Hi DireLink,
Thank you for posting. For future reference, there is no need to post your questions in two locations -- one location is fine.
That said, I'm not sure I understand the questions you are posing. You are able to export listings using Classified Admin > Import & Export > Export Listings, but I'm not sure what you mean by importing them into a new webpage of AWPCP. Are you wanting those to be imported on another domain? If so, then yes, they should be able to be imported assuming that everything on both sites is exactly the same -- the field names, versions, etc.
For your other question, I'm going to need more information for that. Can you please provide steps on how to reproduce the problem, including screenshots of what you see and link(s) to the right pages to start from?
That will allow us to find the issue the quickest. Please let me know.
