Hello,

I need some help sorting out this error:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/new/Archive/phplogin/includes/main/header.php:3) in /Applications/MAMP/htdocs/new/Archive/phplogin/register.php on line 71

I've included the code below, can someone please help me figure this out. I've been working om this issue for 4 hours now and I read on these forums that this is an issue with white spaces, but open this with multiple editors and there seems to be no white spaces.

Any help is much appreciated as always.

You can't redirecct after output to the screen (via php or html). Place all your php in an include file or before the doctype declaration. If your php creates output, save it to a variable and then echo it out in the appropriate place in the html.

There isn't any echo before header(). This peice of code:

echo 'Your account has been successfully created!';

should not run because of the if condition:

if (isset($_GET['success']) && empty($_GET['success'])) {
   echo 'Your account has been successfully created!';
} else {

Do you think this is a problem with the code or white spaces?
