Everything works except USPS

Let's start with a fix for that error:

Then, delete all the error log files in /logs and try again and see what issues come up in the /log directory ...

Excellent, fixing the timezone issue fixed it. USPS now works as it should. The only issue I see in the error log is:

[26-Mar-2014 22:53:00 America/Chicago] PHP Warning: Invalid argument supplied for foreach() in /home/xxxxxx/public_html/includes/modules/pages/checkout_shipping/header_php.php on line 191

Any idea what this is?

Could you look in your directory /logs and see what the debug logs are when you hit the blank page?

[In2Deep]

No more blank page, fixing the timezone issue fixed it.

Does this mean your shipping is working now?
