Curse of the dual orders - IPN & PDT (on Windows IIS)

[robax]

Hello all,

I'll try and make this easy to read:

Setup:
PHP5.x on FastCGI, MySQL5.x, Server 2008 x64, IIS 7.0

I've set up a fresh ZC 1.3.8a purely for the purpose of troubleshooting a PayPal IPN problem. Nothing is installed other than two test products and the basic settings to make PayPal IPN work.

Problem:
Paypal IPN orders have no products in them. If PDT is enabled, then two orders are listed, the second now with products.

With only PayPal IPN enabled:

• Paypal processes payment
• Order is visible to customer and admin
• No products are in the order
• No entry on IPN screen
• User ip shows as 118.92.182.28 - 66.211.170.66 (buyer - paypal)

With PayPal IPN and PDT enabled:

• Paypal processes payment
• Order is visible same as above
• A second order is also visible
• Products are in the second order
• Entry appears on IPN screen
• User ip shows as 118.92.182.28 - 118.92.182.28 (buyer - buyer)

Notes:
I've listed the user ip's there because I noticed that they are different in each case - one with the Paypal ip and one without - thought it might provide a clue.

Each order has a unique ID showing that each purchase with PDT enabled creates one incomplete order and a separate complete order.

Debug Logs:
My debug logs here show one or two purchases with PDT off and then enabled for the last one (I think).

Additional notes:

1. During setup, I had the error described in the following thread and applied the code fix - seems to work.

2. The following thread of mine regarding curl time-outs resulted in discovering that my new dedicated server has a strange connection problem specifically to zen-cart.com. My host, Server Intellect, has thus far been unable to figure out why, but I've not found any other sites that have the problem, and Paypal.com also loads fast, so I'm unsure whether it even matters. The difference can be seen on the two curltest.php links above. The first, to Zen-Cart.com is slow, but the second, to PayPal, is fast.

Questions:
If the above-mentioned connectivity issue to zen-cart.com was also affecting Paypal payments, then would that perhaps create the result I'm seeing?

I either need to get just IPN working, or use PDT and stop it from creating two orders.

Thanks for any advice on this.

If you are hosted by GoDaddy:

See this and the referenced links: http://www.zen-cart.com/forum/announ...php?f=149&a=10

I hope this is the answer... Thanks to Dr Byte!

Thanks for the reply Stuart.

It's my own dedicated server at Server Intellect. I've been through every thread and troubleshooting guide here and have eliminated pretty much all of them before making this post.

I'm hoping the doctor will be able to interpret the problem from the logs.

Oh, one more thing to add.. I run DotNetNuke systems on the same server and PayPal IPN payments work fine with those. I guess that implies that connectivity to PayPal must be ok.

The slow page-load problem mentioned at the end of the first post is now resolved, but this has not fixed the Paypal issues detailed above.

I'm getting desparate.. can anyone read debug logs?

[robax]

I had the domain turned off for a couple of days so those links would have been dead - I've just turned it on again now.

How does one go about dealing with an issue like this? I've done absolutely everything I can think of and am sitting here with nowhere else to go.

Anyone? please?

While I've seen a few people report this, I've never actually been able to make it happen first-hand on a clean install ... so I've never found a 'fix' for it.

[robax]

Thanks for the reply DrByte,

I've got it happening right here with a clean install. It's a fresh cart, nothing but a couple of products and my paypal info in it. I made it purely for troubleshooting this.

Were you by any chance able to check the debug logs I posted... is there a clue in there perhaps?

I looked through them, and the debug emails, but I don't know enough to pinpoint the issue.

I've pretty much resolved every other issue that has arisen and am stuck on this one.

Thank you for any further assistance
Rob

[DrByte]

There's nothing obvious in the logs

[robax]

Ok, thanks for checking anyhow.

I think the only direction for me now is to try and find someone who is successfully running a similar setup. I'll report anything I find.

Regards,
Rob
