If you installed it from a script https://codeberg.org/bookstack/devops/raw/branch/main/scripts/installation-ubuntu-24.04.sh, then most likely your php is processing php-fpm. To apply the php.ini settings in the application, you need to restart the php-fpm service (systemctl restart php8.3-fpm.service)

Another factor to check is that you're editing the correct php.ini file since there may be multiple.
Following the above, where fpm is used you'd need to alter the fpm config, which would typically be located somewhere at /etc/php/8.3/fpm/php.ini on a PHP 8.3 based install using FPM.

Thank you! I originally changed /etc/php/8.3/cli/php.ini, not the php.ini file in the fpm directory /etc/php.8.3/fpm/php.ini

After changing /etc/php/8.3/fpm/php.ini and restarting the php-fpm service, I can now upload larger size files.

Thank you again @wowagsm and @ssddanbrown , you’re awesome and so is BookStack!
