Answer 1

try to change your form open in to this
<?php
echo form_open(base_url('User_Authentication/user_login_process'));
?>

Answer 2

For anyone who face the problem of The address wasn't understood when clicking a link for example, just make sure to add http:// to the $config['base_url'] value, in the case of the question above, you should replace :
$config['base_url'] = 'localhost:8087/hris/';
by
$config['base_url'] = 'http://localhost:8087/hris/';
Hope this help :)
