Hi..I'm a newbie.
I want to ask.. I'm watching the tutorial code abou creating a blog.But there was severals error.I am using codeigniter 1.54 and has already downloaded the 1.61
1. scaffolding matters :
I can't create a new records using the URL
2. when I'm trying to call a view file.The URL stacks
for example :
when it supposed to be http://localhost/ci/index.php/blog/insert_comments/
