I'm running Apache v2.4.27 X64 for serving PHP files and it was running fine until today that I'm seeing `500 Internal Server Error`.
Surprisingly nothing noticeable is logged neither in PHP error log file nor Apache's. I attempted to set `LogLevel warn trace8` and found this: [Wed Jan 23 12:06:58.344368 2019] [fcgid:warn] [pid 13700:tid 1180] (OS 109)The pipe has been ended. : [client 127.0.0.1:54040] mod_fcgid: get overlap result error [Wed Jan 23 12:06:58.344368 2019] [core:error] [pid 13700:tid 1180] [client 127.0.0.1:54040] End of script output before headers: index.php But I can't realize where I should look for the problem. What can I do to debug this? Thanks
