<?php
/* @var $this yiiwebView */
/* @var $form yiibootstrapActiveForm */
/* @var $model frontendmodelsSignupForm */
use yiihelpersHtml;
use yiibootstrapActiveForm;
$this->title = 'Signup';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="site-signup">

在控制器SiteController中，在操作actionSignup()您使用：
$model->save()
您的模型不会扩展类ActiveRecord因此它没有方法save()。
从控制器中删除此$model->save()，无论如何您都在方法signup()中保存用户。
