   I tried looking at the wiki.wordpress articles and I got no where. I am so confused. I followed the steps and everything, but when I tried to publish a test post, I got an error. I'll include the my-hacks.php file here. Can someone help? Thank you. Here is the error:
   Warning: Cannot modify header information - headers already sent by (output started at /home/spirit89/public_html/my-hacks.php:3) in /home/spirit89/public_html/wp-admin/post.php on line 158

$text = preg_replace("#$acronym(?!</(ac|sp))#", "<span class='caps'>$acronym</span>", $text);
}
return $text;
}
add_filter('the_content', 'acronymit');
?>

   I hope someone can help. Thank you again.

   Okay, there should be no whitespace or new lines outside of the PHP tags. The my-hacks page on the wiki spells this out.

   If the error is before the first < then you have whitespace there as allusion has mentioned.
   There should be nothing before the very first < and nothing after the last >
   What is contained actually in between those tags matters little as long as the code is correct.

   I have the same problem.
   Hack file only contains
   <?php ?>
