Support » Plugin: WP eCommerce » SetExpressCheckout API call failed

  • Hi,

    We have a website which uses the WP E-Commerce plugin and it has worked perfectly for over a year now. But recently, the site admin updated to the latest version of this plugin and we have hit a stumbling block.

    Everything works fine up until checkout. Whenever the user clicks ‘Purchase’ they are met with this error.

    SetExpressCheckout API call failed.
    Detailed Error Message:
    Short Error Message:
    Error Code:
    Error Severity Code:

    I can confirm that it is the latest version of the plugin. I have also done the whole process of deactivating other plugins/theme etc, but that has shed no light on the issue.

    Any help would be much appreciated.
