Move everything that outputs text to *AFTER* the header() call
(or just delete it, as the text won't be seen anyway).

This includes:

- A blank line outside <?php ... ?>
- A blank line in an include file outside <?php ?>, especially
at the start or end of the file.
- A space or tab outside <?php ... ?>
- Invisible unicode characters inserted by an editor before <?php
- Warning or error messages output by anything you call before
header().
- <!DOCTYPE declarations
- html

If it tells you where the output started, look there and delete the
offending text. It is likely white space of some sort.
