title: Debug Toolbar in Codeigniter 4 not working
body: <p>I installed Codeigniter 4.0.2 and did following changes:</p>
  
  <p>1- <code>CI_ENVIRONMENT = development</code> in .env file</p>
  
  <p>2- <code>SetEnv CI_ENVIRONMENT development</code> in .htaccess in public folder</p>
  
  <p>3- Added <code>$useKint = true;</code> in main index.php file in public folder</p>
  
  <p>When I open at localhost, welcome page is rendered but no Debug Toolbar is rendered. Am I missing anything? </p>
