我正在使用Magento2，当我登录我的网站时，我收到了这条消息。
处理您的请求时出错 指定无效 父 ID (Magento_Backend：：mgs) 错误日志记录编号： 1307308720759
这个网站运行良好，但最后我运行查询并重新编译，然后这个问题开始出现......
以下错误日志详细信息

只需修改位于/vendor/magento/module-cms/etc/adminthml/menu下的菜单文件.xml
<add id="Magento_Backend::mgs" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::mgs" action="cms/block" resource="Magento_Cms::block"/>
这是它的外观
<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
<menu>
<add id="Magento_Cms::cms_page" title="Pages" translate="title" module="Magento_Cms" sortOrder="0" parent="Magento_Backend::content_elements" action="cms/page" resource="Magento_Cms::page"/>
<add id="Magento_Cms::cms_block" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::content_elements" action="cms/block" resource="Magento_Cms::block"/>
<add id="Magento_Backend::mgs" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::mgs" action="cms/block" resource="Magento_Cms::block"/>
</menu>
</config>
根据错误，mgs 没有任何父 ID 名称，因此它会抛出错误。
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
<menu>
<add id="Magento_Cms::cms_page" title="Pages" module="Magento_Cms" sortOrder="0" parent="Magento_Backend::content_elements" action="cms/page" resource="Magento_Cms::page"/>
<add id="Magento_Cms::cms_block" title="Blocks" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::content_elements" action="cms/block" resource="Magento_Cms::block"/>
</menu>
在上面的代码中parent="Magento_Backend::content_elements"将显示在内容菜单中，因此请为您的菜单提供有效的id，然后它将起作用。
