Note: This change only applies for testing via PayPal sandbox environment. This does not affect any live PayPal transactions.
PayPal has recently upgraded their sandbox environment so the previous method of IPN (Instant Payment Notification) validation will not work anymore. We have upgraded our plugins to work with the new PayPal sandbox changes. If you are testing with PayPal sandbox and having an issue with IPN validation then please upgrade the plugin in question by doing the following:
1. Deactivate and delete the currently installed version of the plugin(s).
2. Download a fresh build of the plugin(s) from here:

3. Upload and activate this version of the plugin(s). The specific update instruction for the plugin in question can be accessed from here:
