10415 - Transaction Refused because of an invalid argument

We managed to set up the Pay Per View plugin (added the API credentials) and added the short code to the page. The button gets generated. After click on it we get message to confirm the purchase. Once we did that we get "10415 - Transaction Refused because of an invalid argument. A successful transaction has already been completed for this token." Can you please let us know what does this mean and how to avoid this error in the future.

Thank you

    Hi @sam,

    There are a few possible causes here. The most likely is that you could be using the site in test mode, but with a live PayPal account (or vice versa) Try double checking your settings to make sure you're in the correct mode.

    The developer for Pay Per View recently posted an explanation for a user with a similar error here if you'd like to take a look.

    You can also try clearing your browser cache (and cookies) or trying another computer to see if this makes a difference.

    Let me know if you need any other help here!
