Magento system.log“警告：SimpleXMLElement”-（adminNotification / Model / Feed.php）

Magento让我再次陷入困境！在/var/log/system.log中，我看到以下警告，但无法找到原因。按照时间戳记，似乎它们都在同一时间触发，所以也许这是一个特殊的动作，它引发了24行警告...有关如何调试的任何想法？

看来是什么东西破坏了adminhtml feed模块。

原因可能是第三方模块正在检索无效的XML。

检查您的站点代码是否包含任何扩展的类Mage_AdminNotification_Model_Feed。

找到之后：

1. 尝试禁用该模块（中的app/etc/modules/）。
2. 清理system.log。
3. 查看错误是否消失。

对每个模块重复此过程。确定哪个模块造成了问题之后，您可以对其进行编辑config.xml并注释掉触发通知的观察者。

我还将建议与模块的开发人员联系，并就此问题通知他们。
