I am not sure what is the reason of my problem. In some cases my PHP
script successfully saves data in it's own (script's) log. But there
is no corresponding record in Apache access log. Why? The error log is empty. mod_fcgid/2.3.9 Apache/2.4.6 (CentOS) PHP 7.1.3 Apache config <VirtualHost 127.0.0.1:8080> ...
