Magento管理员-客户编辑页面不再工作

当我尝试使用Magento后端管理编辑客户时，在console.log中会出现以下错误，并且页面的后一部分永远不会加载

屏幕截图显示了它的显示方式（注意页眉正在加载，但之后什么也没有）

--更新-- 这里是我的customer.xml

代码在第92-97行

if (Mage::getSingleton('admin/session')->isAllowed('newsletter/subscriber')) {
    $this->addTab('newsletter', array(
       'label'     => Mage::helper('customer')->__('Newsletter'),
       'content'   => $this->getLayout()->createBlock('adminhtml/customer_edit_tab_newsletter')->initForm()->toHtml()
    ));
}

一旦这段代码被注释掉，页面就会按预期呈现，因此它肯定与这段代码中的某些内容有关。上面数组中的“内容”中包含的内容有问题。我将很快发布该视图

--更新-- 如上所述，问题100%是由上面的以下行引起的

'content'   => $this->getLayout()->createBlock('adminhtml/customer_edit_tab_newsletter')->initForm()->toHtml()

下面是来自该管理块的代码：

您有500个内部服务器错误，因此有3个地方需要检查：

检查apache/nginx日志以查看错误消息

检查var/report文件夹

在浏览器中，查看页面源并滚动到底部

---

如前所述，这是我将尝试做的

• 检查apache/nginx的错误日志，并滚动到底部以查找最新的错误，此错误日志可能非常庞大，具体取决于它的使用时间。您可能希望删除它，然后在它触发错误并写入日志文件时让apache重新创建它
• Magento在会话和缓存方面可能存在问题。注销Magento中的任何管理/客户会话，清空管理中的所有缓存
• 清空所有浏览器会话/缓存等。。我甚至可能使用不同的浏览器
• 查看console.log并使用stack trace选项，这将突出显示它所采用的路径，在查看调用的javascript时非常有用
• 在您提到的视图/文件中，一次注释掉一行或一个块，然后再次运行页面，看看会发生什么。这可以帮助您缩小“问题代码”的范围

---

希望这有帮助

你能从app\design\adminhtml\default\default\layout\customer.xml？@KeyurShah中放置你的customer.xml吗？我已经在我最初的postCheck中添加了customer.xml，以查看来自本地或社区的模块是否覆盖了类Mage\u adminhtml\u Block\u customer\u Edit\u Tab\u Newsletter\u
