In the includes\modules\payment\as2checkout.php find line 181 or do a search for Process_2checkout (there is only one) the line will look like this
zen_draw_hidden_field('x_receipt_link_url', HTTPS_SERVER . DIR_WS_CATALOG . 'process_2checkout.php');
take the "S" out of HTTPS_Server so it reads
zen_draw_hidden_field('x_receipt_link_url', HTTP_SERVER . DIR_WS_CATALOG . 'process_2checkout.php');
This solved both the issue of the blank page as well as the issue of MODULE_PAYMENT_2CHECKOUT_TEXT_ERROR_HASH_MESSAGE
What this line does is overwrite the settings that you have in 2CO, they call it an X-Return if you look in thier forums.
