javascript - 选择站点管理时，moodle 中 JSON 中位置 0 处出现意外标记 <

Question

我们刚刚迁移了一个 Moodle 网站，除了管理链接网站管理之外，大多数情况下一切都运行良好。单击后，它将继续旋转 3 分钟，直到超时并显示 500 错误和错误消息 Unexpected token < in JSON at position 0 。这是控制台输出:

moodle/lib/ajax/getsiteadminbranch.php 500 (Internal Server Error)

我禁用了 JS 来打开调试，但无法复制错误，直到我注销并重新登录(JS 打开)。

重复上述步骤，我得到了更详细的控制台日志

好像挂了

moodle-block_navigation: Loading navigation branch via AJAX: siteadministration

这是堆栈跟踪:

SyntaxError: Unexpected token < in JSON at position 0 at JSON.parse >()

该代码可以在旧环境中运行，但显然我在新环境中仍然缺少一些东西。任何帮助将不胜感激。

我通过取消 php.ini 中的注释解决了这个问题:总是_populate_raw_post_data = -1
