I was able to fix this. This peace of code did block it:
/**
* Redirect back to homepage and not allow access to
* WP backend for Subscribers.
*/
function rkk_redirect_admin(){
if ( ! current_user_can( ‘edit_posts’ ) ){
wp_redirect( site_url() );
exit;
}
}
add_action( ‘admin_init’, ‘rkk_redirect_admin’ );
