Remdex, have you tested hppg with paypal recently?
Getting this error at checkout:
Fatal error: Call to undefined method SOAP_Fault::getAck() in
/var/www/html/plain_hppg/r1387/lib/core/lhshop/paymenthandlers/paypal_handler/handlers/process.php
on line 101
Guessing Paypal have changed something in the API.
Let me know if you have any idea what might be the problem, and I'll report back on anything I find.
Cheers
