Why did i get this error ? Where is the error ?

Answer 1

Not like this:
$route['default_controller'] = 'products/index';
$route['products/create'] = 'products/create';
$route['404_override'] = '';
Do it like this:
$route['default_controller'] = 'products';
$route['404_override'] = '';
Do not specify method, because than CI will look for "index" controller in application/products folder which does not exists. If you specify path in route than it looks for a path.

Answer 2

Just a reminder (esp to myself).
If you create something like this
$route['products-view'] = 'products'; //refer to products.php
$route['products-create'] = 'products/detail/create'; //refer to products/detail.php
you will face a routing error when trying to open products-create because you have a file name products.php, it will think there is a method named detail in the file. CI will open to products and there is no such method name detail and will throw error.
