Shopp payment gateway no longer working

[manifestphil]

The Shopp payment gateway appears to no longer be functioning properly. After checking out, the user is directed to a confirmation page, then upon confirmation back to the checkout. This results in an infinite loop. The actual transaction appears to happen as it charges the card and it shows up in Click and Pledge.

I'm using WordPress 3.7.1 with Shopp version 1.2.9.

I've also verified that I'm using the most recent payment gateway for Click n' Pledge.

Good day!

We tested the plugin and can't duplicate your issue. Would you please let me know if you have installed the latest version of our app?

https://github.com/ClickandPledge/wordpress-shopp

We think you may have the old version of the app installed with the newest release of Shopp!

If you have the latest version and still have issues please give us access to your site by creating a support ticket at http://help.clickandpledge.com. Please include a link to this thread and user login information so we can review your installation.

Updating to the latest version of the payment gateway seems to have resolved the issue.
