Paypal Pro express checkout, Credit Card checkout

On the one before last step and need help please since this is the first time I am implementing e-cart. The checkout wizard does not ask for a Token when entering API credentials. Is this required ? When I see server behavior for Paypal Express checkout the Token seems empty. What do I put in here ?

When I submit the checkout Paypal Express results in pp_checkout_failure.php

But When I submit data through Credit Card checkout, the page hangs, just blank page.

I do not reach the pp_confirm.php or the confirm.php

Paypal Sandbox aco**** setup, Business Test account setup works (I can enter Sanbox Test site for both buyer and seller account).

Express Pro checkout takes me into Paypal TEst site, I can login to test buyer account I set up, but when I continue, instead of seeing the pp_confirm page I see blank page. (hangs)

Reading the threads, I update the PP_ECO_PHP.php, but this reads as version 2.20 and what I downloaded last week with my new subscription is ecart 5 with a version number of 60.0
-----> updating, I downloaded this and still I get same blank page for pp_confirm
------> same for credit card transaction as well

The URL link for pp_confirm.php after paypal pro site, brings back a .../pp_confirm.php?Token=EC(negative number) & PayerID = (number)

Requesting a start of a private ticket, so I can point you to the site where I have this installed. Since I do not know much PHP.

Really appreciate any help.
Thankyou.

I have created a support ticket so we can look into this issue further.

Should I post the links to the site where I have this here ?

I forgot to mention that I am not using powercart. I created a simple store store.php (one item) with a ADD to cart button (as per the Display Manager). Clicking this takes me to cartnew.php (as expected). On this page I inserted the Checkout Wizard. I see the item in the cart. All buttons update, delete, continue shopping, and checkout work. Checkout takes me to the checkout.php . With the Express Checkout button on top and Credit card checkout to follow. Then the behavior is as described. Onwards to Paypal, then blank page instead of confirm.php. Not sure what files to send, but attaching the two confirm files to start with. Thank you so much for helping me debug this.

on the confirm page and the pp_confirm page, find the following lie:

$BurstSize = undefined;
  $BurstTime = undefined;
  $WaitTime = undefined;

and change it to:

$BurstSize = 200;
  $BurstTime = 1;
  $WaitTime = 1;

if you still have problems, add the following to line 1 of both pages:

<?php

error_reporting(E_ALL);

ini_set('display_errors','on');

?>

Hi, Jason:

That did work, for Paypal Express Pro. I get the pp_confirm.php and I get pp_checkout_success.php after that. But how did you calculate TAX without asking for shipping address in PayPal Express Pro ?? it straight came to pp_confirm.php with 8.25% california tax calculated.
----->probably my Test User account login is set up as San Jose, CA

But if I go back into store and add another item to cart, for checking the credit card payments, it presents a cart WITH THE TAX calculated. ?? Not right because TAX must be calculated AFTER I specify shipping address (I selected 8.25% if the item is shipped within California and nothing added if outside).

-----> This I thought I should self medicate with some session unset and clear Cart, not successful, since I don't know where to place the commands and the <php tags to go with it. please help.

Is it remembering past session variables ??

I also had to revert to the PP_ECO_PHP.php script that I downloaded version 60 with my subscription for this to work the version 2.2 (fix mentioned in thread for eCart 5) did not take me into Paypal sandbox.

Attached files.

VISA card checkout leads to transaction failure checkout_failure.php AFTER confirm.php attached image of page please see Ticket Thread.

Thanks

Please read personal ticket for updates and file attachments. sessions and cookies have been unset, to clear the cart with some code that you posted on different thread. I included the lines in
pp_checkout_success.php and checkout_success.php.

Still having trouble with "Transaction Failed" with Credit card checkout, after confirm.php.

PLease take a look. Thank You.

Added code as suggested on ticket. Posted the checkout_failure.php response on the ticket page.

Also, after transaction failure response, the cart continues to hold previous items.

Should I add the clear session, cookies and cart code to checkout_failure.php and pp_checkout_failure.php as well ?

Thanks
