I am confused as I would like to configure a stripe payment. I followed this instructions, but I don’t have the same screens. I don’t have Gateway setup.
I tried to put an account ID from stripe by generating a new API key but that did not work. My client reported me this error:
Il y a eu une erreur lors du traitement de paiement . Veuillez réessayer plus tard. Message:
$config must be a string or an array.
How could I enable the Gateway setup for Stripe?
