Warning: Cannot modify header information - headers already sent by

Hi Ray,

Am having to rework this (very ancient) site to put a captcha in - using DB v2.

Form loads ok but when it's submitted, you get: Warning: Cannot modify header information - headers already sent by (output started at /home/sarahhb/public_html/contactme.php:4) in /home/sarahhb/public_html/webassist/form_validations/wavt_scripts_php.php on line 85

URL is sarahhb.co.uk/contactme.php

Any ideas?

Thanks
Andrew

The issue is the blank line on line 3 of the attached page. You can't have blank lines before a redirect... it is best to make sure you don't have any blank lines or spaces in your php code above the <html> tag.

Can't modify header solution

just put this at the beginning of your page and it should stop the Can't modify header errors

<?php
ob_start();
?>
