我在magento 2中收到此错误。我没有做任何更新，这个错误突然出现了。
我看到我必须删除＆＃34;＆＃34;＆＃34;属性，但我在哪里可以找到？

您无法在referenceContainer中添加after属性。如果您想移动Container，请使用它。
<move element="element name" destination="where you want to move" after="">
答案 1 :(得分：1)
我想，您使用的是magento2.2版本。在这个版本中，布局xml有一些修改。您无法在after代码中使用before和referenceContainer属性。
要解决此问题，您必须从after中删除before和referenceContainer属性。
您可以使用move标记重新排列布局
答案 2 :(得分：0)
您必须向扩展程序支持添加新故障单，因为这是扩展程序问题。您可以检查路径app / code / vendor_name / module_name / view / frontend / layout /
中的所有xml文件答案 3 :(得分：0)
正如zed所说，这看起来更像是对v2.2.x的升级问题，因为它们使布局格式更加严格，并且之前允许的一些内容不再存在。
before代码中的after和referenceContainer属性不再有效。
我们还发现move标记内也不再允许使用referenceBlock标记。
要查找这些问题的位置，我进入vendor/magento/framework/Config/Dom.php文件并在_initDom()方法输出$xml变量，以查找每个异常的第xxx行的实际xml代码就像OP上面的那个。
