<?php
header("Location: index4.php");
?>

You PHP script is encoded in UTF-8 with BOM (the BOM is the problem).

BTW:
You must use an absolute URI in "Location", not only a filename.

Read the manual of your editor how to save UTF-8 files without BOM.

(Or don't use UTF-8 if you don't need it.)

Check that you don't have any text, including whitespace (spaces, line feeds, carriage returns, tabs) outside of the <?php ... ?> delimiters.

AFAIK you can't save UTF-8 files without BOM in notepad.

headers already sent by ... is a typical error in php.
It occures from blank space before <?php or after ?>.
Therefor, you need to use proper text editor(Not Notepad).

Else, you saved php file with UTF-8 with BOM.
So, you have to save it with UTF-8 without Byte Order Mark.
