Fresh install, CI_DEVELOPMENT in .env not work

This is not the direct cause of your issue, but you should use appstarter:

Code:

composer create-project codeigniter4/appstarter ci-news

See https://www.codeigniter.com/user_guide/i...stallation

I don't know why your environment is still production.

Try this:

Code:

composer create-project codeigniter4/appstarter ci-news
cd ci-news/
php spark env development
php spark serve
