Internal Server Error after update to latest version
After updating Mollie in OC3 to the latest version, whenever a customer tries to complete the payment there is an Internal Server Error. In the logfiles I get the following: "2025-08-06 13:22:33 - Error setting up transaction with Mollie: Zorg ervoor dat u een veilige verbinding gebruikt.."
Downgrading back to 13.4.0 made things work normally again.
