【问题描述】：
我正在使用 Yii2 Advanced。今天无需更改托管在虚拟主机上的我的网站上的任何内容。我在所有网络上的页面底部都收到了这条消息
Fatal error: Uncaught yii\web\HeadersAlreadySentException: Headers

我没有在我的控制器中使用echo，因为我确实读到了控制器内部的回显会导致此错误。但我做了检查，但我的所有控制器内都没有任何回声
我的控制器：SiteController.php 是

【问题讨论】：
-
所以它出现在您网站上的所有
controllers和actions上？或者只是SiteController？ -
在页面底部的所有页面上
-
在所有控制器和操作上
-
你能把网址显示一下吗？如果那里有
echo，你有没有查看frontend/web/index.php？，你是通过composer update升级Yii版本的吗 -
hmm 这里没有什么奇怪的地方，尝试注释掉
<?= $content ?>部分以检查异常是否属于内容部分并缩小范围
