Express checkout button , which is send cart detail to Paypal without user Login.

Now , I have getting problem with express checkout button which is not send cart order detail to the Paypal payment screen.

Here is the screen shot of my site express checkout button screen.



After click on checkout button it will redirect to Paypal screen as below , but not take cart item information with Paypal It is display blank in Paypal screen as below.



Problem occurred while customer was attempting checkout with PayPal Express Checkout button only.

Any one have solution for this issue..?

I don't recall seeing other reports of this problem (with PP express. IPN is another story), and you haven't really given us enough information to even take much of a guess.

For example, the comment "Problem occurred while customer was attempting checkout" is *suggesting* to me that this may well be a a single isolated case rather than a problem for all customers. However, I also have a gut feeling that it is happening with all customers that try to check out in this manner.

It would help if you didn't make us guess. :)

However, since any guess is possibly better than no guess at all, my next question to you is exactly how did you do the upgrade? Is it possible that the upgrade wasn't 'complete' and the current site is still using the older 1.3 PayPal modules?

Have you tried enabling the PayPal 'debug' options and inspecting the log files for any clues, oddities or errors?

In fact have you looked at or tried *anything* at all to help debug the problem?

As a general guide, it is usually safe to assume that on a stock/unmodified system it all works as advertised, so the implication is that the problem, whatever the cause, has to be *unique* to your installation, and that is where it gets difficult for us to offer much help because we really don't have any way of knowing exactly what it is that is making your installation different. You are the only person in a position to make this determination.

I/we appreciate the fact that you are probably asking for help in the hopes that there is a quick fix that someone could provide (and this may indeed still be the case if another users happens to have had the same experience and solved it), but without this, the cause could be almost anywhere.

Sorry I can't offer any other help.

Before the upgrade did you.
Record all existing settings in your payment modules?
Uninstall the modules?

Do the upgrade

Reinstall the modules and re-enter the saved settings?

Turn on paypal logging: http://www.zen-cart.com/showthread.p...Logging-PayPal
Then attempt a payment. Be sure it doesn't pass the data.
Then look in the /logs/ folder for the PayPal-xxxxxxx.log files related to that transaction (there could be up to 6 of them, all with the same timestamp).
Post their contents here.

I suspect they'll tell you that line-item details couldn't be sent for some reason. That reason will explain.

Hi ,

Thanks for reply to all.

@ RodG :

This is the problem is a common for all customer not for single customer.

I have upgrade my zencart using follow the below steps :
usm ansh ahz ada.com/blog/how-to-upgrade-zen-cart-1-3-9-to-zen-cart-1-5/

Yes , I have check log file , there is not any error in that , whole Request Headers, Request Parameters and Response array are printed with Approved status. check below log file screenshot.



Also , I have upgrade and test with sandbox mode from setting changes in admin , then it will not allow to test me with sandbox also.
So , I have tested it with live Paypal Detail.

After upgrade Paypal files with 1.5.3 getting error of as below :

Error We are sorry for the inconvenience; however, at the present time we are unable to use PayPal to process orders from the geographic region you selected as your PayPal address. Please continue using normal checkout and select from the available payment methods to complete your order.

SO , I have set back my Paypal Old files in to zen-cart 1.5.3 from Paypal files of 1.3.9 then above problem is solve and payment done , but still Express checkout button problem is their. As I define in my first post of this thread.

Have you stepped through and completed the purchase? The total will be displayed in the ZenCart step 4 of checkout as the message in the PayPal screen indicates.... after selecting shipping method, payment method (nothing to select, since PayPal was previously selected), etc.

The left side PP message that you will see the total before payment is finalized is accurate.
A PP message also appears at the bottom of the rightside panel stating that the order process will be finalized on the "YourStoreName" website. That is after selecting your PP account or PayWithCreditCard.

Having said that, our typical customer will not read any of the text and just assume there is a problem without continuing.

In the case where I can reproduce that screen, YES, 4 PP debug logs are generated at the instance where that particular PayPal screen appears. The logs seem to be related to the math and PayPal having designed their own mathematics rules. Dumbing it down for them.

The PP screen presented seems to be dependent upon the monetary value of the particular items in the cart (in my case).

It's having difficulty calculating totals properly.

I wonder if it's a problem with the low-order-fee surcharge?
