I just started getting this error on my wordpress site when I try and access certain pages. I have checked the3 /custom_functions.php file and I see nothing that looks out of place. Any help would be appreciated. The site is whowillwinthe2012election.com

Warning: Cannot modify header information - headers already sent by (output started at /home/cdunde1/public_html/wp-content/themes/thesis-15/custom/custom_functions.php:1) in /home/cdunde1/public_html/wp-includes/pluggable.php on line 890

Here is the code from the custom_functions.php file

<?php

// Using hooks is absolutey the smartest, most bulletproof way to implement things like plugins,
// custom design elements, and ads. You can add your hook calls below, and they should take the 
// following form:
// add_action('thesis_hook_name', 'function_name');
// The function you name above will run at the location of the specified hook. The example
// hook below demonstrates how you can insert Thesis' default recent posts widget above
// the content in Sidebar 1:
// add_action('thesis_hook_before_sidebar_1', 'thesis_widget_recent_posts');

I'm no Wordpress expert, but I'll give it a shot. My guess is that your functions are being called before Wordpress outputs a header (such as a redirect). This will cause problems because headers are sent after the first character of content has been outputted. It might help to actually echo the values instead of end the PHP and insert them in the file. Try something like this:

<?php
function test() {
    global $whatever;
    echo '<b>some html here</b><em>and lets add that global: '.$whatever.'</em>';
}
?>

Instead of:

<?php
function test() {
    global $whatever;
?>
<b>some html here</b><em>and lets add that global: <?= $whatever ?></em>
<?php
}
?>

Thanks, I tried that and it did not work.
