Trouble returning to page after form submission

That didn't work, I am not sure what is causing the system to add the .php to the link. The error that shows up on screen from CI states:

An Error Was Encountered

Unable to load the requested file: main/contact.php

If it was just trying to simply load main/contact (without the .php) I think it would work perfectly. Why is it addding the php file extension?
