an error occurred while processing this directive
an error occurred while processing this directive 解决方法
问：
访问站点的php文件时，提示[an error occurred while processing this directive]出错，但html文件正常，如何是好？
答：
直接原因之一是执行脚本出错，应该返回出错页(500.php)，但Apache(Server Side Includes)找不到，即有提问中的出错提示信息。
过程：
登录到控制面板，查看出错日志有如下记录：
MAIN error_log:
