CI3 Tutorial Help Needed

Hi,

I've been working through the CI3 tutorial.  I need help tracking down what I've done wrong.  When I go to the form to create a news item and click the button I get '404 Page Not Found Error,' and the URL looks like this:  http://localhost/codeigniter3/index.php/...ews/create

I was expecting the URL to look like this:  http://localhost/codeigniter3/input.php/create, but even if I type in the previous URL, I still receive the 404 error page.  

I've also looked at the database and no entries are being entered from the form submission.  How can I check the database connection? 

Thank you
Timothy
