@joostvanveen Hi Sir. thank you, but i have another problem.

I have a problem when I enter the page http://ci-cms.com/article/

An uncaught Exception was encountered
Type: ArgumentCountError

Message: Too few arguments to function Article::index(), 0 passed in C:\xampp\htdocs\ci-cms\system\core\CodeIgniter.php on line 532 and exactly 2 expected

Filename: C:\xampp\htdocs\ci-cms\application\controllers\article.php

Line Number: 12

Backtrace:

File: C:\xampp\htdocs\ci-cms\index.php

How can i resolve this problem?

Thanks.
