Answer 1

You need to make sure that all the session.php are in the first part of the page. All the header() must be in the first line or make sure that you didnt send something to the browser before the header() part. Check this for more info

Answer 2

This error comes frequently when a coder tries to use the function "headers()", when at least ONE character has already be sent to the user.

You file "session.php" has its error on line 1006, which is very, very far down!

Search for ANYTHING that creates an "output":

ie: echo("text") leads to an output. You can't use headers() after that.

The most common error is a single blank line in the code:

1.
2.

3. $Session = md5()

4. headers(something)

will generate that error: line 2! (there is nothing, sure, but there is a couple CR/LF!

(And I think it is your mistake => "(output started at 2.php:7)" !

Answer 3

It means there is a header() call somewhere after the headers have already been concluded. Move the header() call(s) upward before any page text is sent, particularly before

Answer 4

Its hard to know without seeing your code but it looks like you have an echo before a header statement. Header statements must be before all outputs.



WRONG:

echo 'hello!!';

header('index.php');



RIGHT:

header('index.php');

echo 'hello!!';
