Errors trying to redirect to thank you page
My form works and sends to my email just fine. However, I've had a problem trying to get it to redirect to a thank you page after submission. I used the error code and it came up with these errors:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home5/richwsco/public_html/ym/nova/contact.php:1) in /home5/richwsco/public_html/ym/nova/contact.php on line 88

It still won't redirect to thank you page. What do they mean?
