All we have is info in the Description tab.
Basically what you need to do (after installing the plugin) is go to “WooCommerce > Settings > Product XML Feeds > XML Feed #1” and (if you leave the default settings) click “Create now” – feed will be created instantly (i.e. so you won’t need to wait until automatical scheduled creation is run) and you will be able to check the resulting XML feed in http://yoursite/products.xml.
Hope that helps – please let me know if you have any questions. Also if you wish, you can share an admin account to your server (my email is [email protected]), so I could log in and help you setting up the plugin.
