Your CodeIgniter web application is configured to run with development mode enabled. When your application runs with development mode enabled, detailed error messages with stack traces will be shown on every error that occurs within your application. If disabled, a simple generic error page is shown. It's recommended to disable CodeIgniter's development mode when the application is deployed to production.
To disable development mode set the CI_ENVIRONMENT environment variable value to production in the .env environment configuration file.
# .env CI_ENVIRONMENT=production
