【问题描述】：
所以我昨天正在处理这个页面，我遇到了一些错误，但仍在完成所有内容，但是当我停止时，我加载了页面正常。然而今天当我加载页面时它是空白的，并不是完全空白，但它会在文件中的某个点停止加载内容（见下文）。
现在奇怪的是，如果我把它放在 cmets 中它不会改变任何东西，当我放入所有 php 代码时它甚至不会改变任何东西。所以我有点卡住了......
编辑：所以我才意识到我忘了提供链接，尽管在网上查看时它给出了一个完整的空白页面...... http://hmorreels.hol.es/Morreels_App/index.php/charts 可悲的是，虽然这是一个内部 500 错误，所以那里的信息不多：/
也许你们中的一个人看到了吗？ 我已经把页面放到网上，我把我的代码放在这里...... 本页面使用 laravel 作为框架，但大部分页面都是简单的 PHP。

你能把你的错误日志贴在这里吗？
-
据我所知，我得到了 0 个错误，那么我应该在哪里寻找呢？ （服务器上的错误日志文件 = 空，页面上的错误为空）
