You can set the desired page when do logout from wordpress admin area. For that you have to modify wp-login.php core file of wordpress. Here is the code which needs to be modified:
<a href=”<?php echo wp_logout_url(); ?>” title=”Logout”>Logout</a>
<a href=”<?php echo wp_logout_url(‘$index.php’); ?>”>Logg ut</a>
This will redirect to the index page of the blog when you logout from wordpress admin area. You can set any page which you would like to be.
