For many years, we have maintained PayPal IPN for WordPress as a free plugin. Unfortunately, we are not able to sustain this and continue active development the way we have been.
As of the PayPal IPN for WordPress 2.1.0 update, the plugin is now a paid plugin. You will need a valid license key activated on your site in order to continue receiving notices and automated updates in the future.
We are sorry to make this move, but we hope you can understand why it had to be done. This will allow us to devote more resources to this plugin for implementation of feature requests and other improvements going forward.
PayPal IPN for WordPress
Purchase your PayPal IPN for WordPress license so that you may activate the plugin on your website and receive automated updates.
