I have a confusing behaviour. I can't get any error into log file or screen.
I made a file index.php with content like this: "<?php a();".Normally, I will get message like this: "Call to undefined function a()" but when I called this script on my configuration I got nothing. Only white screen and empty logs.
I checked all rights. I turned on all possible log file. Nothing. Please help me.
