Hello everyone.
My opencart 3.x site is experiencing a big problem.
In a store with 200 orders per day and relatively high traffic, sometimes duplicate products were in orders with the same data (with or without options).
I use journal3 with one-page checkout.
Could you please tell me how to find the reason for the problem.

I have attached it for your review

Not much sure about the issue but it can be due to your checkout module or any related session

Do you have an idea how to find the source of this problem and fix it?

The Journal3 framework is of poor quality, and in particular it's one-page checkout has known bugs. This is not an OpenCart issue. You have to contact the Journal3 support. See also this forum thread.

Could be this issue if not with the Journal3 framework.
https://github.com/opencart/opencart/issues/7375

I've never failed to recreate it in 3.0.x. Ignore the bit about 15+, it does depends on server load, sometimes it happens with just 2 products in the cart and sometimes you need 50+.

I use a quick workaround, but it will probably need additional work for the Journal3 framework.

@ADDCreative, I think you might need to double check that quick workaround - it does not prevent duplicate cart records.
You would have to transfer the items via the cart add function or you will actually generate duplicates that way.

It does transfer items via the cart add function. It has been tested and used on live stores. All it does is move the updating of the customer's cart to just login / register and not every request. Did you try it and have a problem? I'm happy yo look at it again. There is more discussion in this thread. viewtopic.php?t=211273

As above, ask Journal support or pay developers such as ourselves.

This issue is not easy to solve in general you have to take paid support from best theme developer or any reliable developer to solve this
