Your product feed upload won't work if you installed it on your developer site because it's not connected to the Internet. To fix this issue, you'll need to install the Facebook for WooCommerce Extension on your live site instead. Also keep in mind that each of your products need to have a valid description, image, and unique product ID (such as a SKU) for you to be able to upload your products to Facebook.
We are in talks with a few organizations who have very substantial interest and whose values align with ours. As negotiations continue, I may write more updates here as we move along and may be able to announce a new parent org for FMA in the coming weeks. Nothing is set in stone though so we still face shutdown, and if you have questions or want to help, please contact us using the Closure Comment form (at the end of this blog post).
