When all your feeds, without reason, are empty from one day to another than changes are you would need to reset the plugin deduplication counters in order for your feeds to be able to populate with products again.
Follow these steps:
- Go to your “Manage feeds” section of the plugin, It is this page:
- Add the following parameter and value to the URL you are on: &force-deduplication=true, so your URL will look something like this: ../wp-admin/admin.php?page=woosea_manage_feed&force-deduplication=true
- Hit enter, the page will refresh and all counters have been reset
- Now manually refresh your feeds (or wait for an automated update to come by), you’ll find that your feeds contain products again
