Then I went to my backup files and doing a couple at a time (writing down as I went) uploaded them back to my site. For every couple files I changed I would go back to the store and test. I was able to trace the one bad file I had that was causing the whoops..................
SO...........................
I would first try changing these files -
/includes/classes/shopping_cart.php
- /includes/modules/pages/checkout_confirmation/header_php.php
- /includes/modules/pages/checkout_payment/header_php.php
- /includes/modules/pages/checkout_shipping/header_php.php
- /includes/modules/pages/shopping_cart/header_php.php
- /ipn_main_handler.php
and includes/modules/pages/login/header.php.php
if none of those fix the problem you can try starting with the includes folder.
