Language

[jackermann]

Postfinance reports:
Due to the last successful transaction, the language settings are not correctly marked with de_DE.

The language is set correctly in the Gateway.php:
             'Language' => 'de_DE', // ISO Language code

Or is it handed over to another place?

May I ask you where you see that message? In the Postfinance backend?

Also, how do you set the language? You should not modify Gateway.php yourself. Set the language as a parameter instead!

In addition to what I wrote above: Please note, that the Parameter is named language. So maybe it's as simple as changing the parameter name to all lowercase…
