PayPal Express Checkout Returns to Blank Page

[hamburgler100]

Everything seems to be working fine with Express Checkout until PayPal returns back to my site, and I get a blank screen. If I refresh the page, things work correctly, but otherwise, nothing happens.

My site is http://www.southcliffwest.com/shop.

I'm running v1.3.8, and I don't have any add-ons running.

When I run the log, the last item that appears if I don't refresh is this:

Not logged in. Looking for account.
SELECT customers_id, customers_firstname, customers_lastname, customers_paypal_payerid, customers_paypal_ec
FROM upwardcustomers
WHERE customers_email_address = 'kyle@kylegilbert.com'
queryfactoryresult Object
(
[is_cached] =>
[resource] => Resource id #149
[cursor] => 0
[EOF] => 1
)

I just now figured out what was wrong. Customizations I made to the create_account.php file were causing this problem, like mentioned here:
