Duplicate order with same Transaction ID

We haven’t seen that specifically, but we have seen similar things that could be what you’re running into. Basically, if the functions get run twice for some reason this can happen, but the answer why that would happen is elusive.

In your case, the first one was Success, and the second one was SuccessWithWarning. That would mean you should have seen money drop into your account for both of those, but then they would have had different transaction IDs. Can you confirm you only received a single payment from the customer?

Did you have logging enabled in the plugin when this happened? I would need to get a look at those logs to get a better idea of what happened here.

Yes, only one Paypal payment from the customer and logging is enabled.
I’ve opened a ticket on your support webpage.
Thanks!

I’ve encountered a very similar issue as Rob. In my instance, two orders were duplicated for $29.75 and two orders were duplicated for $41.90. All four have the same transaction ID. On the PayPal side of things, it’s showing that one payment in the amount of $41.90 was received.

That is extremely odd. So you’re saying that you had 2 separate people order, but they were both entered twice in WooCommerce, and all 4 orders in WooCommerce had the same PayPal transaction ID?

Are you running any sort of caching or CDN service that could be interfering with session data?

Hello! Actually, the same person placed two different orders that were duplicated. All four orders had the same transaction ID.

Ok, that tells me something funky is going on with the session data. Are you running a caching or CDN service of any kind in WordPress or on the server directly?

What sort of hosting environment are you on?

What are some common CDN services? I don’t have any caching services enabled.

HostGator is my hosting provider.

Are you on a basic shared host, a VPS, or a dedicated server?

Here are my plug-ins. Any potential culprits?

I’m on a VPS. We’re planning to upgrade to a dedicated server.

Essentially, the site lies dormant for most of the month, save one 24-hour period (yesterday through today) in which as many as 500 customers are on the site at once buying products (scented wax). As you can imagine, this caused significant server issues.

Yeah, I’m thinking something quirky must have gone wrong on the server during that heavy traffic time. It’s really hard to say what that could have been without digging into server logs.

The PayPal transaction ID is stored in session data, so on the surface it seems like something could be going wrong there.

Another thing that could be possible is maybe a situation where the customer made a purchase successfully, and somehow their session was not cleared after that order completed.

Then they do a new order, which fails for one reason or another, but the original transaction ID from the first order is still saved in the session data, so that winds up getting saved in the new, failed order as well.

Again, though, that session data should be cleared when an order is completed, so if that sort of thing was happening we’d have to figure out why exactly it wasn’t getting cleared.

That’s where plugin conflicts could come into play. This list is a little tough to read. Can you go to WooCommerce -> System Status, and then run the system report in there? It will give you a nice report to copy/paste for me so I can read the plugins a little more easily, as well as some other details about the server.

Thank you so much for all your help!

: Learn how to update outdated templates

You have a bunch of WooCommerce template files that are showing up as “out of date”. This means your theme needs to be updated to work with the latest version of WooCommerce.

I don’t know for sure if that’s the root of this problem, but it’s certainly the first thing I would want to get resolved to eliminate it as a possibility.

We’re having a very similar issue actually. Although I think it’s maybe a WooCommerce issue rather than specifically your payment plugin.

We are using Stripe and PayPal express and experiencing similar issues (both are the official woothemes plugins).

I wrote this post on GitHub (https://github.com/woothemes/woocommerce/issues/10453):

Basically we have established that on some occasions, especially under heavy server load, both PayPal Express and Stripe orders are getting duplicated. If it happens with a Stripe payment then we will actually receive two payments, however seeing it happen with stripe is more rare. If it is with PayPal then it is almost exclusively with PayPal express (using the woothemes plugin) and has actually on occasion led to three or four copies of an order. When it happens with PayPal express there will be two identical orders showing in the WooCommerce orders list with different order numbers but the PayPal transaction ID will be listed as the same for both and there will be only one payment in PayPal.

This has happened a few times when the server was not under heavy load at all. In all cases the customers have not intended to make these duplicate orders at all.

We have also had the odd few orders where they have been successfully paid on PayPal Express but on the website are still showing as “Pending”.
