Paypal Error - TAX_TOTAL_MISMATCH

[audiorock]

Hi,

Joomla 4.4.4, VirtueMart 4.2.10 11010, PHP 8.1.27


I'm having a problem with PayPal payment. Confirming the payment the following error is released in FRONTEND (this active debugging on the front-end side is terrible for the customer who purchases!!!)

Code Select Expand

1 vmdebug createOrder no OrderId Var0:

Hi,
Any news?

Get the latest version of VM and the plugins - released a few days ago

[audiorock]

I have already installed the latest version of the VM plugin (4.2.10 11010) and the problem persists!

the problem only occurs when I add multiples of the same item to my cart.

Do you use TAX or VAT?

[audiorock]

Hi,

we use VAT set at 22% (operator VATtax +%) and discounts in some products (operator DBTax -%)

Hi,
if it can be useful, with parameter "with Breakdown" in OFF, the problem not appears!
