Php 无错误日志数据的内部500

我得到一个内部500错误，它似乎没有写入任何错误日志供我调试。在我的access文件中，我可以看到我正在连接到服务器，但它会以一个内部500进行响应

My.htaccess文件需要执行以下操作：

改写成。如果没有https请求且不是本地主机

其余部分非常简单，是从标准的WHMCS.htaccess文件复制而来的

该错误特别发生在#Products rules中-如果我通过超链接打开链接，它也会间歇出现并显示为打开链接，但直接从浏览器访问页面会出现错误

有什么想法吗

 RewriteEngine On

 # Rewrite to HTTPS where needed / possible:
 RewriteCond %{HTTP_HOST} !=localhost
 RewriteCond %{HTTPS} !=on
