Paypal IPN Auto Return URL not working correctly

[truffles]

I'm hoping someone can help me. I'm setting up Zen Cart for the first time (one of the best I've seen) but am having problems integrating Paypal IPN.

- I'm using ZC 1.3.8a.
- I'm on a Godaddy shared hosting server and called to confirm part 80/443 are open.
- I've checked the setup three times with Paypal and in Zen Cart.
- When I do a test check out of my test product at $.01, paypal transfers the fee between accounts correctly but the Auto Return URL opens to a blank page (but it is the correct URL with some appended parameters)

Here are the errors I see in the log file:
Mar 29 2009 20:46 -- IPN INFO - POST VARS to be sent back for validation:

What is the likely problem?
