I am having problems editing the Atahualpa theme functions file to recognize anything. In the example below I'm trying to replace the dashboard logo and nothing happens. No matter what function I put in here nothing ever happens. I've tried putting my code inside the main php body as well as creating a new php area as seen here. I've spent hours on this and can't figure it out. Thank you.
<?php
// Replace dashboard logo
add_action('admin_head', 'my_custom_logo');
function my_custom_logo() {
echo '
<style type="text/css">
#header-logo { background-image: url('.get_bloginfo('template_directory').'/images/32x32_Wings.png) !important; }
</style>
';
}
?>
