Here is the Easypopulate 4 support thread:

http://www.zen-cart.com/showthread.p...Support-Thread

It's not yet in zencart plugins but first post has a link to github to get it.

BTW, Easypopulate 4 will work even if another easypopulate is installed, as it is independent. Just make sure you're using the correct spreadsheet with the correct easypopulate when uploading, as there are some differences. Example: easypopulate 4 handles the categories^subcategories differently; there are in the same column as I show with the "^".
