Cannot add new payment type (Worldpay)

-- HikaShop version -- : 4.7.1 [2302220839]
-- Joomla version -- : 4.2.8
-- PHP version -- : 8.0.27
-- Browser(s) name and version -- : Chrome 110.0.5481.105

Hi,
I'm setting up a new website with a new install of Hikashop and the Worldpay plugin (yes, its enabled) and I get a Call to undefined method error when clicking on the plugin name in the list of payment plugins after clicking on the New button in the payment methods screen.
I have come to Hikashop because you have a Worldpay plugin and my client will only use Worldpay.
Not sure what I am doing wrong, or if this is a bug.

Thanks! That seems to have solved it, and I'm impressed with the speed of your response, too!
