CI_ENVIRONMENT = development not working

@romzine Do you mean the following line does not work?
https://github.com/codeigniter4/CodeIgni...nt.php#L14

Or you have customized "app/Config/Boot/development.php"?

Yes, that line does not work!
It looks that the Fastpanel way how they manage php settings on multihost (multiple domains) server, for each virtual host, that overrides CI4 settings related to php ini.
