RANDOM White Page when Credit Card Checkout?

[lat9]

Yep, that addthis plugin is "polluting" the javascript/jQuery pool and the AJAX checkout is very dependent on that pool being "clean".

Yikes......alright, I will see if we can eliminate that from the checkout pages. Not sure exactly how to do that since it's part of our global header file (in common/html_header.php).

Until I can figure it out, I'll keep the PSS setting turned off as swguy suggested.

Is there a php FLAG or something I can put in the HEAD area to determine if we're on the checkout_payment page, and therefore not have that part of the code outputted? Let me know. If not, I'll do some more hunting around.

Could put it within the following php check:

<?php
if (empty($_GET['main_page']) || substr($_GET['main_page'], 0, 9) != 'checkout_') {
?>
//script code
<?php } ?>

... or, more succinctly:

<?php
if (empty($_GET['main_page']) || strpos($_GET['main_page'], 'checkout_') !== 0) {
?>
//script code
<?php } ?>

Where's the love for $current_page_base ?

One other thing to check ... @Jeff_Mash, what is the store's setting for Configuration->Gzip Compression? If that's enabled, try disabling the compression and re-enabling the AJAX checkout. I'll bet that it's that setting that is causing the issue.
