"Warning: Cannot modify header information"

  • I’m coding a website for a friend, and I keep getting this error whenever I try to submit something new (like a new post):

    Warning: Cannot modify header information – headers already sent by (output started at /home/cpiekarz/public_html/URBANSAFARIPHOTOGRAPHY.COM/wp-content/themes/safari/functions.php:1) in /home/cpiekarz/public_html/URBANSAFARIPHOTOGRAPHY.COM/wp-includes/pluggable.php on line 881

    Any ideas how to solve this?

    Usually caused by adding whitespace before or after opening and closing php tag.

    It says that the error is in the functions.php file of my “Safari” theme in line 1. I’ve messed with this file for the last hour. I’ve done the following:

    1. Made sure there are no spaces at the beginning or end of the file near the tags

    2. Attempted to take out all the functions.php code except the opening and closing php tags, with no extra spaces before or after

    3. Pasted the function.php codes from other WordPress themes into my file

    but none of these options work.

    The ONLY thing that works is deleting my functions.php file completely, but I need that file so that I can use post thumbnails in my posts.

    Any suggestions?

    All I need my functions.php file for is so that I can have post thumbnails. Here is my code:

    <?php

	add_theme_support( 'post-thumbnails' ); 

?>

    There are no extra spaces, but I keep getting the error.

    Check your header.php page. Make sure there are no white spaces on top.

    Thanks for the tip. I checked, and I don’t think there are any extra spaces. Here is my header.php page:
