PayPal Payment Standards orders not generated

[terraGirl]

A shop that was upgraded from 1.5.1. to 1.5.3 now has failing PayPal Payment Standards orders.

The payment is taken by PayPal, the customer is returned to the checkout success page but the order is not entered into the site's database, no order ID, no email, no record of the order itself in the shop.

The PayPal debug log shows:

------------

The shop is Zen Cart 1.5.3; and has 1 module that modifies core files "Super Orders". Uninstalling "Super Orders" did not fix the problem.

Other payment modules (e.g. the credit card module Realex) work fine, orders are generated.

There are no PHP error logs showing under /logs/

Site is running PHP 5.4

Bit stumped on this one, help appreciated.

Many thanks, Edith

Edith,

I have had some issues with this as well. However, from what I have been old this is a Paypal Standard/IPN problem that is solved by moving to Paypal Express. It appears to be a timeout/connection issue between ZC and Paypal's IPN system. I have not move to Paypal Express just yet as I have some issues with how it treats addresses but I am going in that direction. I lost a $1,000 order due to this about 6 months ago.

Cheers
Chris

In the update from 1.5.1 to 1.5.3 were the override files of the template updated to reflect the changes made in the equivalent template_default files or to address those changes?

The template is the "all business" template http://www.zen-cart.com/downloads.php?do=file&id=1174 and the template files appear okay when compared against the default 1.5.3 files.

As gtkccf said, the only fix for this problem I'm aware of is to switch to the much-more-stable Paypal Express.

Just to say Express does work perfectly, no issues, so we are using this now.

I am still a bit perplexed as to why Standard worked on 1.5.1 and doesn't after upgrade to 1.5.3 but there's a time pressure to get this sorted, so we're going with Express.

Thank you everyone who replied!
