Authorize.NET payment module - 4.0 Error

I'm having the same "Incorrect Content-Type" error. The problem appears to stem from the browser POST-ing to /checkout/paymentmethod but then being GET-redirected to /checkout/paymentinfo. Manually changing the action of the form to /checkout/paymentinfo solves the error and allows the payment to proceed.

I am also getting same error.

InvalidOperationException: Incorrect Content-Type:

                            EngineContext.Current.Resolve<ILogger>().Error(exception.Message, exception, currentCustomer);
                        }
                    }
                    finally
                    {
                        //rethrow the exception to show the error page
                        throw exception;
                    }
                });
            });
        }

Only way process the order with Authorize.net is use One Page Checkout.
Regular checkout getting error.

Bump, any resolution to this? I am still facing the same issue and OPC isn't an option.

This is an issue with the View Component Request set to Form instead of Query. You would need to recompile the

Nop.Plugin.Payments.AuthorizeNet plugin.

- go to: Nop.Plugin.Payments.AuthorizeNet code
- change Components/PaymentManualViewComponent.cs : 40

from

            var form = Request.Form;
to
            var form = Request.Query;

- recompile the plugin
