 * I’m designing a new child theme for Buddypress 1.5.1 using WordPress version 
   3.2.1, following the directions [here](http://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/).
   I’ve just uploaded the functions.php file with the code
 *     ```
       if ( !function_exists( 'bp_dtheme_enqueue_styles' ) ) :
           function bp_dtheme_enqueue_styles() {}
       endif;
       ```
   
 * as it says on that page, but I’m getting this error:
 * **Fatal error: Cannot redeclare bp_dtheme_ajax_querystring() (previously declared
   in /home/sddia/public_html/wp-content/plugins/buddypress/bp-themes/bp-default/
   _inc/ajax.php:17) in /home/sddia/public_html/wp-content/plugins/buddypress/bp-
   themes/bp-default/_inc/ajax.php on line 81**
 * Any idea what is going wrong here?

 * Also interested. Found one thing: not all the themes return this error, only 
   the most advanced ones. Those based on BP Default work ok. Still curius how to
   make it work.
