One-Page Checkout [Support Thread]

[lat9]

Was this issue corrected? I recently installed version 2.4.1 and still experience this issue.

FWIW, noting that the previously-reported issue was in this (https://www.zen-cart.com/showthread....25#post1387125) posting.

I've not yet had a chance to reproduce, hopefully in the next few days.

Actually you stated you were able to reproduce it in post:

https://www.zen-cart.com/showthread....95#post1387195

And then posted:

The issue was addressed on github and I thought fixed unless I misunderstand?

It's been a long couple of months ... in what way does the issue persist on your site?

Hi @lat9, I gathered some information for the recent duplicated orders after OPC is installed:

Example 1:
Paypaldp
fedexwebservices

Order placed time:
06/23/2022 11:37:35
06/23/2022 11:37:36
06/23/2022 11:37:37

These orders are not marked as guest-checkout
Domestic shipping address

Example 2:
Paypaldp
fedexwebservices

Order placed time:
06/22/2022 19:59:29
06/22/2022 19:59:30

These orders are not marked as guest-checkout
International shipping address

Example 3:
Paypaldp
fedexwebservices

Order placed time:
06/02/2022 17:27:30
06/02/2022 17:27:31
06/02/2022 17:27:31

These orders are marked as guest-checkout
Domestic shipping address

So it looks like the duplicated order only occurs when the customer is paid by credit card (paypaldp) and selected FedEx shipping method (which takes a little bit longer time to load than USPS).

Do you think increasing AJAX timeout time will help? Currently it is set to 5s by default.

Increasing that AJAX timeout might help, but without understanding the underlying cause of the duplicates, it's a patch at best. Where did you find that fedexwebservices shipping method?

Hi @lat9, thanks for your reply.

I just increased this time from 5s to 6s and see how it works.

I downloaded the latest FedEx plug-in from numinix. I'm using v1.8.1 now.

I checked my server log and my site updated the latest fedex module on May 18, 2022. I installed the latest OPC back on my site on June 2, 2022. Actually the duplicated order issue is started on June 2, 2022. No issues between May 18 and June 2.

I updated my site to 1.57d on April 18, so my paypaldp module got updated at that time.

Since they only show 1.5.6c supported, you may want to contact them for an upgrade.
