I trying to update from J3 and VM3 to J4.4.2 and VM4.2, using PHP 8.1
When I am in the cart and want to checkout, I get to a page with error 0 - invalid value for setState.
I get this with and without a OPC check plugin, so also with the standard Virtuemart checkout.
Someone got an idea?
I found the cause of the error.
It's a bug in the payment plugin I use. I will contact the plugin developper,
Error message data:
500: invalid value for setState in file ..\plugins\vmpayment\cgpgeneric\cardgate-clientlib-php\src\Entity.php:96
