Blank Page during checkout - "Uncaught SoapFault exception" in fedexwebservices.php

[dremhmrk2]

Hello everyone,
I am using the most recent version of zen cart and have many add-on's installed.

Today we had a customer who was getting a blank page when checking out via paypal, and after checking my cache folder for the logs, I found a number of interesting logs I don't understand.

Here's a selection of my logs:

Im getting one for SOAP:

GetExpressCheckoutDetails, Elapsed: 718ms -- Success

I'm very concerned about this... because I have no idea how many people are getting blocked, I see a TON of these error logs.

You're having problems with your FedEx addon. Contact FedEx

Your PayPal log for the GetExpressCheckoutDetails step (2nd of 3 steps) looks fine. Nothing to go on there.
