Hi @hedij! This forum is intended for questions about the core WooCommerce plugin. It sounds like you are having issues with a different plugin, and not the main WooCommerce one that we support here.
The doc you linked to talks about the integration of the AWeber service with WooCommerce. For that integration to work, you need the AWeber Newsletter Subscription extension, as stated in that link you shared:
First, if you have not already done so, install the AWeber Newsletter Subscription plugin on your WordPress site.
If you have purchased and installed that plugin but are having trouble configuring it, we recommend you reach out to the corresponding support team. You can contact them by going to WooCommerce.com, logging in to the account that owns the license, and then heading to the Support page. Please note that you will only be able to access support if you own an active license for that paid extension.
I hope this helps! I’ll close this thread now.
