I've changed `$config['index_page']` to

```
$config['index_page'] = ''

```

and also updated my .htaccess file content to:

```
RewriteEngine on
RewriteCond $1 !^(index\.php|public|\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1

```

but I can't access controllers without putting index.php in my url.
So what should I do next?
