Double orders with Klarna

[hazael]

Hi,
I have nonstop double orders after using the "Klarna Checkout Enhanced" payment system + "VirtueMart One Page Checkout" from
https://joomlapro.com/extensions/virtuemart
The seller believes that his plugins work properly.

I updated virtuemart, changed the template and nothing changed. Where to look for a problem?

Joomla final version.
VirtueMart 3.6.10 10211
PHP 7.4.6

Latest stable VirtueMart is 3.8.2 10325

Maybe change PHP to 7.3 version

Has it ever worked ? New site, updated site ?

As Jenkins said, test with PHP 7.3

The older 7.3 PHP version does not change anything.
I changed to 7.2. I'll see if anything helps here. :-/
