/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
* - or -
* http://example.com/index.php/welcome/index
* - or -
* Since this controller is set as the default controller in
* config/routes.php, it's displayed at http://example.com/
*
* So any other public methods not prefixed with an underscore will
* map to /index.php/welcome/<method_name>
* #see http://codeigniter.com/user_guide/general/urls.html

On line 73 of the code you posted it looks like the if statement for
$this->email->send()
is failing, which then runs this:
else
{
//error
echo $this->email->print_debugger();
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">There is error in sending mail! Please try again later</div>');
redirect('contact/index');
}
I would check the configuration in Email.php - in my Codeigniter 3 project it is located here:
html/system/libraries/Email.php
At the bottom of this Codeigniter 3 API page is some info about print_debugger and about the Email library. It should help you get in the right direction.
