Ran into this same question myself. Did some digging through the files and I decided just to do a flatout edit of the one of the files.
You may have to redo this every time an update comes along – but ah well. I’m not familiar with how WordPress handles plugins – if someone can do so, that’d be great.
Just go to your blog/wp-admin/index.php
Right under:
require_once(‘admin.php’);
Put:
if (!current_user_can(‘level_10’) ) wp_redirect(“profile.php”);
Yea, it’s a very tiny edit. ??
