function zm_redirect_wp_admin() {
if ( is_admin() && is_user_logged_in() && !current_user_can( 'manage_options' ) && !current_user_can( 'publish_pages' ) && !current_user_can( 'publish_posts' ) && ( !defined( 'DOING_AJAX' ) || !DOING_AJAX )  ){
wp_safe_redirect( home_url() );

wp_safe_redirect( 'https://zmingcx.com/' );

&& !current_user_can('publish_pages') && !current_user_can('publish_posts')

$current_user = wp_get_current_user();
if($current_user->roles[0] == get_option('default_role')) {
