Magento-尝试创建新的Adminhtml页面时出现错误404

我使用的是Magento 1.9.0.1，我创建了一个新的扩展，在其中我在“管理”面板中添加了一个新选项卡，请查看图片

这是我档案里的东西

在：/app/code/community/VivasIndustries/SmsNotification/etc/config.xml中：

<?xml version="1.0"?>
<config>
  <modules>
    <VivasIndustries_SmsNotification>
      <version>0.1.0</version>
    </VivasIndustries_SmsNotification>
  </modules>
  <global>
    <models>
        <smsnotification>
            <class>VivasIndustries_SmsNotification_Model</class>
        </smsnotification>

关于

提前感谢！

它应该在您的XML文件中。因为您可以在错误页底部看到，它正在寻找不同的地址（。/Smsnotification/。，但是您的控制器位于：。/Smsnotification/。）。应该在这部分：

<about translate="title" module="smsnotification">
                    <title>About</title>
                    <action>adminhtml/smsnotification_about</action>
                    <sort_order>11</sort_order>
</about>

关于
管理HTML/smsnotification\u关于
11

尝试使用smsNotification，看看它是否有效。

Magento有许多不同的404页面——知道哪一个可以帮助别人帮助你：另外，请提供我的Better404模块（免费）一次尝试--这将使Magento的MVC-404页面在跟踪问题方面更加有用，谢谢你的回答！我更新了我的问题，并在安装插件时添加了404错误的图片！你能告诉我问题出在哪里吗？提前谢谢！我照你说的做了，我收到了错误报告：那么现在是你的控制Magento找到了ler，但找不到其中的类。请尝试将控制器类名更改为：

class VivasIndustries\u SmsNotification\u Adminhtml\u SmsNotification\u AboutController

<?php

class VivasIndustries_SmsNotification_Adminhtml_AboutController extends Mage_Adminhtml_Controller_Action
{ 
    public function preDispatch() 
    { 
    return Mage_Adminhtml_Controller_Action::preDispatch(); 
    } 

    public function indexAction() 
    {
        $this->_initAction();
        $i8ee45e0018a32fb1a855b82624506e35789cc4d2 = $this->getLayout()->createBlock( 'Mage_Core_Block_Template', 'my_block_name_here', array('template' => 'vivasindustries/smsnotification/about.phtml') );
        $this->getLayout()->getBlock('content')->append($i8ee45e0018a32fb1a855b82624506e35789cc4d2); $this->renderLayout(); 
    } 
    protected function _initAction() 
    { 
    parent::_initAction(); 
    $this->_setActiveMenu('smsnotification/about') ->_title(Mage::helper('smsnotification')->__('About')); 
    return $this; 
    } 
}
