php - 如何解决过多的重定向？

Question

我在这个页面上得到一个 ERR_TOO_MANY_REDIRECTS，我知道它的这个脚本有两个原因，1.它控制页面 2.它发生在我编辑这个脚本之后。这是我的脚本：

<?php


    $userloggedinok = _wp_get_current_user();


if ( $userloggedinok  != 0 ) {
    if (current_user_can('bypass_maintance')) {
        allowintowebsite();
    }
}

function allowintowebsite() {
    wp_redirect(home_url('/'));
}
