php error on wordpress site

[system]

The following is the error on my Wordpress Admin Login screen
Warning: Cannot modify header information - headers already sent by (output started at /homepages/29/d366823984/htdocs/wp-content/themes/WarehouseCarpets/functions.php:1) in /homepages/29/d366823984/htdocs/wp-login.php on line 400

I am not sure how to fix this. I can give you the code I have.

Is this a fresh Wordpress install?

Do you have any plugins installed?

That error is caused by data being output by your php code (or the files that include() some php file) before the header() function is called.
