Cannot redirect after HTTP headers have been sent (PayPal Standard)

Hello All,

I did a test live check out with PayPal Standard.


When I click on Confirm and it redirects to PayPal

It goes to PayPal ok everything looks ok.

But, when I check the error log I see this error:

Also the system thinks that the order went through.

So it sent an receipt email and everything.

I do notice through if the user go to their account and go to Orders

and click on details

it does tell them that the order was not completed and gives a button to click on to pay for the order
with out having to start over with the cart even through it was emptied.

Just need to figure out a way to stop the "Receipt" email from being sent and

Instead send an order incomplete email with instructions on how to complete the order or
ask for feedback on why its incomplete.


I guess a quick fix is to edit the "Receipt" email.

Like this:

If you had completed your order then this is your Receipt Email.

If you did not completed your order you can do so by going here:

Login first and go to:

http://www.shop.kbdavis07.info/orderdetails/8

Or just click on the Orders link and then details.

On the left side click on the orange button:

"Complete Payment"

If you have any questions please contact us.

The Order Placed Email Template has the wrong Subject:

OrderPlaced.CustomerNotification

Order receipt from %Store.Name%.


Should be Order Placed from

I'm starting to think that this error isn't connected to any functionality issues...

I'm also getting the HTTP header error did anyone find a resolution to this?
