nginx – Where are PHP8 syntax error logged?

I installed LEMP with PHP8 on Ubuntu 24.04 and was able to host a WordPress website.

The only thing I can’t figure out is where PHP errors are logged.

For example I created a PHP page with an error:

when I open this page browser displays this:

no error messages appear in /var/log/php8.3-fpm.log.

I added

error_log = /var/log/php8-error-log.log

to /etc/php/8.3/fpm/php.ini:

restarted php-fpm service

sudo service php8.3-fpm restart

and opened my page with the error, but the file /var/log/php8-error-log.log was not created at all.
