Cannot modify header information - error message

[leo.angart245561]

I am testing Universal email.

Using a very simple form.
I get the email back on screen with this error message below.

Cannot modify header information - header already sent by /Email/WAEU-Email-test-5.php

No email is received.

What is the problem?

Usually that error gives a line number and it means that you have a blank line or space on that line preventing a redirect below.

The email not being recieved is most likely a separate issue, since this error is more likely from the redirect below the email which should already be sent.
