The first thing you will need to connect AWeber with WP Users Pro is go through the authorization process.
Click on the AWeber link, then you have to click on the “click here to connect” link.
Please note: A new link will be opened and you will be taken to the AWeber Authorization page.
You have to allow access to your AWeber account, this way the plugin can access to your subscribers list.
Once you have granted access you should see the following screen. Although, you’re already connected to AWeber at this point you will need to set your desired list.
