Capybara your webserver has a global php.ini which is never empty. Its location depends on the operating system or hosting company. On a self-hosted system, it might be found in a place like /etc/php/8.3/apache2/php.ini On a managed hosting it might not be accessible and instead edited through a GUI.
If you want to raise the limit, you might be able to do it by adding a line to the local php.ini in your site folder if that's a feature your host provides. This file was not created by Flarum.
