How to re-open Checkout Wizard once it's been run?

Urggh. Something's not right with the Checkout Wizard - blank white page when we get to checkout. How do I re-install it or is there a way to open the existing occurrence of it? For example, if you need to change the PayPal details?

Thank you.

You can change the paypal details by editing the Payment Gateway Settings server behavior.

You can't re-enter the wizard. You can only re-open the individual server behaviors that the wizard applies.

If you add this to the top of the page you may be able to see the error instead of a blank page to lead you to the solution:

<?php
ini_set('display_errors',1);
?>

The error is referring to line 2 in confirm.php which is this line:
<?php require_once("webassist/ecart/checkout/credentials/gateways.php"); ?>

Checking the webassist directory, there is no /credentials/gateways.php directory? :(

Hope you can help.
Thank you.

Are you using a payment gateway? If you are doing a checkout without payment then that file isn't needed and the reference can just be deleted.

It will likely be PayPal Payments Pro so I'm thinking that we will need that file. How do I create it?

Thank you.

The payment server behavior is applied on the confirm.php page. If you need to change the settings you can edit it from that page.

If you ran the wizard without the payment gateway at all it may make sense to run it again in a sub-directory and then copy over the confirm.php page or just delete the pages and run the wizard again.
