WordPress 插件激活触发致命错误

Question

我知道有很多这样的问题，但我找不到任何与我的案例相关的具体问题。要么就是这样，要么他们没有得到答复。

我编写了一个非常简单的 PHP 脚本并上传到一个 zip 文件夹中的 wordPress 站点，当我尝试激活插件时，WordPress 给我一条消息：“无法激活插件，因为它触发了一个致命错误。”它实际上并没有给我任何错误信息。我将 WP_DEBUG、WP_DEBUG_LOG 和 WP_DEBUG_DISPLAY 都设置为 true，但这些都不会在假定的错误时更新。看来我无法找出致命错误到底是什么。

我不知道如何处理这个问题。任何帮助都会很有用。

    exit();

  else{

    exit();

这个插件的总体思路是，它将挂钩到 wordPress 网站上的 javascript 生成的 A-tag，CURL 发布到另一个站点以登录，然后重定向到该站点，希望绕过用户身份验证，因为由于 CURL，用户将已经登录。

此代码对我有用。 但是有一个问题，为什么你添加了 exit();在 else 条件下，它正在破坏插件激活过程。

请检查并告诉我。
