  1. Most recent browsers honor F12 to bring up their developers' console; press F12, then select the Console tab. OPC logs status of its AJAX-handled calls to the browser's console.
  2. Turn on the OPC debug via the plugin's Configuration menu. That will generate a log that tracks the OPC processing for the page, into a .log file in your /logs directory. The file is created on a customer-by-customer basis.
  3. Check the /logs directory; are there any myDEBUG-*.log (other than the checkout_one ones) files? They might tell a tale.

As a final suggestion, try comparing /includes/modules/payment/paypaldp.php to the version shipped in Zen Cart 1.5.4 (since you're blazing new territory on ZC 1.5.1!).
Hi Cindy - many thanks for your response (I must have had a Seniors moment with 'no' instead of 'not')

I followed your suggestions and here are the results - in 2 (or more) separate posts as too much text for one post according to the error message;
