PayPal Payments Advanced - Field format error: Request is too large to process

PayPal Payments Advanced - Field format error: Request is too large to process

I just encountered an error with eCart. It only appears to happen when there is a significant number of items in my cart. In my case (8) items will trigger the error. After much research found the error "Field format error: Request is too large to process". I sent an attachment with the complete response message for your reference. Is there a way to NOT send them the complete list of items? Would that help, or would that screw up what I want to insert into the database after the transaction completes? IE. Thumbnail URL, Description, Etc.

It looks like you can process transactions without passing the itemized list to paypal in order to resolve this problem. If you give me FTP access I can look at it and let you know what lines you can edit to test.

It looks like you can just update line 63 of cart/confirm.php

It currently reads:
$WAGatewayResponse = PP_PayAdv_Post($vars,$dragboatsdotcom,$test=false);

Try updating it to:
$WAGatewayResponse = PP_PayAdv_Post($vars,false,$test=false);

Not sure the error is the same, but it is still giving me the "Transaction Not Completed" response message, but now I seem to get it even if there is only 1 item in the cart.

Can you send me the full error like you had before? I'll see if I can spot it that way. I couldn't check out on the site to test on my own. Is there a way for me to do that now?

I deleted that code right after I uploaded and tested the page due to security issues. What code do I use in order to post that response again?

Just add:

php:
<?php

@session_start();
var_dump($_SESSION);
?>

Where and on what page should I place that code.

On any page after you have the error. It can be on the failure page, or even create a separate page you can visit after and it will display the information needed.
