当我提交站点地图时，管理员端突然出现白屏。这是我的错误日志显示的内容。
PHP Fatal error: Call to a member function getId() on a non-object in /home/investor/public_html/yourvaporizers.com/app/code/core/Mage/Adminhtml/controllers/SitemapController.php on line 99
PHP Fatal error: Call to a member function getCollection() on a non-object in /home/investor/public_html/yourvaporizers.com/includes/src/Mage_Adminhtml_Block_Sitemap_Grid.php on line 47
不是编码员，所以不知道如何解决这个问题。
更新 - 我应该添加整个错误代码。

最佳答案
这是该文件的第 99 行
#File: app/code/core/Mage/Adminhtml/controllers/SitemapController.php
$this->_title($model->getId() ? $model->getSitemapFilename() : $this->__('New Sitemap'));
因此，看起来 Magento 正试图在 $model 变量上调用 getId，但 $model 不是一个对象。如果我们查看分配/定义 $model 的位置，在库存系统中，我们会看到
#File: app/code/core/Mage/Adminhtml/controllers/SitemapController.php
$model = Mage::getModel('sitemap/sitemap');
那么，您的错误可能有两个原因。首先，您或其他人在您的 Magento 系统中安装了一个扩展，它做了一些事情(类重写、行为更改)，在尝试实例化 sitemap/sitemap 模型时导致了可恢复的错误。这导致 $model 为 false，并导致您的错误。
第二个是有人更改了此文件或站点地图模型文件(在 core 或代码池之一 community、local) 并做了一些导致 $model 未定义的事情。
调试步骤包括比较新下载的副本，以及禁用与站点地图功能相关的任何扩展(或最近安装的)。至于
Not a coder so have no clue how to fix this.
更好的问题可能是
Why is a non-coder working with a system that, for years, has proven you need to be a coder (or willing to learn) to work with.
