# Slightest change to function.php causes error

 * I’m using a code to make a ratings plugin appear in my custom taxonomy.
 *     ```
       if ( $terms ) {
       			foreach ( $terms as $term ) {
   
       				if ( in_array( $term->name, array( 'Services', 'Book Designing', 'Coaching and Consulting',
       						'Copywriting', 'Critiquing', 'Editing', 'Freelance Writing', 'Literary Agent',
       						'Marketing and Promoting', 'Proofreading', 'Publishing' ) ) ) {
       					$found = true;
       					break;
       				}
       ```
   
 * It should appear in all the categories listed here, but I noticed that instead
   of “Literary Agents,” the plugin developer wrote “Literary Agent,” and so the
   ratings don’t show in that category. I simply added an “s” to the end, and I 
   get this error on the front end:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/curveson/public_html/wp-content/themes/template_New_Child_Theme_1/functions.
   php:1) in /home/curveson/public_html/wp-content/themes/BT/framework/class/class_layout.
   php on line 152
 * It doesn’t matter what I do in this file. The smallest of changes creates an 
   error. Can someone help me with this? I have no idea how to change Agent to Agents
   without an error. I’d really appreciate some help. Thanks!

 * In your `functions.php`, the opening PHP tag (`<?php`) must be the very first
   thing in the file, with no spaces, tabs, line breaks, etc. before it. Can you
   check to make sure you didn’t accidentally add a space or anything else before
   the opening tag?

 * Thanks for responding so quickly!
 * There are no spaces before the opening tag. In fact, everything was working fine
   before I added the ‘s’.
 * At first the developer told me what custom code to use in my functions.php. Every
   time I added the code, I got that error. I used Filezilla, which is usually perfect
   for me. The developer then added the code for me with no problems.
    Now I want
   to add a single ‘s’ and I get an error. I’m baffled.

   before.

 * Copy all of the code from your functions.php file and paste it into PasteBin:
   [http://pastebin.com](http://pastebin.com)
 * Then link us that
