I'm using WordPress 3.5.1 and twentyten.
I want to remove the support for custom background. I found this text: http://codex.wordpress.org/Function_Reference/remove_custom_background
but i'm a newbie in php, so I dont know what to do whit the information.
I guess I should use this code
<?php remove_custom_background() ?>
but what to do with it? where should I put it?
