No connection could be made because the target machine actively refused it.

Hello,

I am trying to setup my online site offline in my localhost yet I am getting this error message:

Code:

A PHP Error was encountered
Severity: Warning
Message: mysqli::real_connect(): (HY000/2002): No connection could be made because the target machine actively refused it.
Filename: mysqli/mysqli_driver.php
Line Number: 202

Line: 292
Function: require_once
A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: C:/xampp/htdocs/pureline/application/controllers/Site.php

I am not sure why that's happening?
