We are using Codeigniter 4. We restarted Apache (Apache/2.4.37) after found it was suddenly stop working, Site page is working fine before the Apache dead. After restart, all pages displayed same error "You have an empty or invalid base URL. The baseURL value must be set in Config\App.php, or through the .env file." We didn't change any config file setting and confirmed there is baseURL configured in environment file. Could anyone suggest what's problem is it?
Thank you very much.
