 * [15 years, 5 months ago](https://wordpress.org/support/topic/problem-with-functionsphp/)
 * I am having been adding some features to my site through the functions.php however
   in the last day or so it has started giving me this error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home4/rhythmsn/public_html/wp-content/themes/rhythm2012/functions.php:269)
   in /home4/rhythmsn/public_html/wp-includes/pluggable.php on line 890
 * Any helps would be much appreciated. Here is my functions.php

 * I hesitate to answer, because this isn’t quite my cup of tea, so I could be wrong
   here. My hunch was that the problem is in your add_actions. Then I saw that you
   have this code in there twice:
 *     ```
       add_action( 'admin_menu', 'create_meta_box' );
       add_action( 'save_post', 'save_meta_box' );
       ```
   
 * I’m new to hooks and add_actions – but if I guess correctly, you only need those
   once.

   <?php` or after the closing `?>` in functions.php
