Problems with checkout_confirmation.php

[adamll1]

Hello, I've recently noticed a strange error on a site that's been functioning all year... To my knowledge nothing has changed on the server- certainly not the files... From time to time using IE- mostly v6 but v7 as well- as I go through the order confirmation process (shipping address screen, billing address screen, confirm order and enter payment details screen) the Payment Information does not show up: Billing address summary, Delivery address summary, CC owner, CC number, CC exp date, etc is just not there... Looking at the source code for the page when the info doesn't show up doesn't indicate any problems in the markup, there's just a whole section missing... IE 6 gives me a Runtime error, "'document.checkout_payment.payment.length' is null or not an object"... As best I can tell the problem seems to have something to do with this statement: (or at least this is where the code cuts out...)

 

<?php
 if (is_array($payment_modules->modules)) {
   if ($confirmation = $payment_modules->confirmation()) {
?>

 

Refreshing the page sometimes loads the missing data- I've also noticed a strange error on log in, (limited to IE6) where the initial log in gets "page can't be displayed", refresh gets the login screen with "error: no match for e-mail address and/or password" as if it were an empty form being processed...

 

I've made some changes in the admin to try and address this, though I really don't know what's what- "use cache" is false now, "force cookies" is true...

 

Thanks in advance for any thoughts on why this might be happening...
