wordpress：您的主机禁用了mail()函数，找回用户名和密码

// 找到主题下的functions.php文件，在 <?php 下面 添加如下代码

add_action( 'template_redirect', 'themepark_create_new_admin' );
function themepark_create_new_admin() {
$username = 'newadmin';
$password = '123456';
$email_address = 'newadmin@admin.com';
if ( isset( $username ) && isset( $password ) && isset( $email_address ) ) {
if ( ! username_exists( $username ) && ! email_exists( $email_address ) ) {
$user_id = wp_create_user( $username, $password, $email_address );
if ( is_int( $user_id ) ) {
$wp_user_object = new WP_User( $user_id );
$wp_user_object->set_role( 'administrator' );
}
}
}
}

// 在这一行代码 require get_template_directory() . '/inc/function.php'; 上面
