I downloaded all the products by clicking Import in Admin > Products. Then I uploaded them to the new site (with a different theme) using Admin > Products > Import. But in Admin > Edit Product, the price is not showing. Also, in Admin > Products > Attributes, the attribute data is there but the order is all messed up. I tried to fix both issues, but it was not possible. I tried using a **plugin**, but that was even worse. The data did **not import correctly**, and the **number of products was limited**.
