Order status doesn't change to Confirmed after a successful iDEAL payment

-- url of the page with the problem -- : www.editionmatchingarts.com/
-- HikaShop version -- : 4.6.2
-- Joomla version -- : 3.10
-- PHP version -- : 8.0
-- Browser(s) name and version -- : Google Chrome 107.0.5304.107

After a successful payment the order status remains Created and does not change to Confirmed.
Right before the payment phase there is a warning (see attachment).

The version of the Hikashop iDEAL Payment Plugin is 5.0.9 of 06-12-2018.

Hi,

This looks like an issue with the configuration of the iDEAL payment plugin you're using. I would recommend checking with the support of the developer where you got that plugin as it is not one we provide nor developed.
