It is just a misuse, not a bug. See the screenshot. It shows not found: \Config\Home::index. The controller should be App\Controllers\Home. If you use ::class keyword, you must specify the correct classname. You need to learn PHP namespaces.

Yes I am new to this stuff but could you help in understanding why in some route it works and the in others it doesn't and i have to use the old technique/syntax. This is my routes.php

Because you don't understand PHP namespaces. It is not CI4 thing, but PHP thing. CI4 and modern PHP uses namespaces everywhere. So I recommend you learn namespacing completely.

Read:

• https://www.w3schools.com/php/php_namespaces.asp
• https://www.php.net/manual/en/language.namespaces.rationale.php

P.S. If you show your code, do not use screenshots, but use copy and paste, please. And use Markdown properly.

Thank you for the knowledge shared by you.

And Yes i have got it I realized now why you kept saying namespaces even though I used it but only on the RegisterController and I should have done the same for LoginController and Home as well.

And yes I have not used Markdown so much.
