PHP Error log woes

Hi all.

I cannot get my PHP error_log statements to show ANYWHERE. Very frustrating.

I have set “php_admin_flag[log_errors]=on” in the PHP FPM settings. I can see that is fine when I run phpinfo();

But where would the log file be? I try to set it with “php_admin_value[error_log]=/logs/error_log.txt” and can see the value is set in phpinfo(); but of course no file appears.

Can anyone help??

Many thanks!
