extload

If you are using any of the following payment gateways, or are using CartThrob Subscriptions, you must configure your extload.php file.

  • Mollie
  • SagePay Direct (CartThrob Subscriptions Only)
  • SagePay Server

Your extload.php file is found in themes/user/cartthrob/lib/extload.php. Open this file in your text editor. Make sure your your $system_path variable at the top of the file is set to your EE system folder. You may also set the $system_server_path instead to set a full server path to your EE system folder. You should also set the $third_party_themes_path variable if necessary.

In the CartThrob control panel, on the Payments settings page, you will see a message in your payment gateway settings indicating whether extload.php is configured properly.
