First, lets test that your site is working properly.
In the powerstore site, create a new file name phpinfo.php.
add the following code:
<?php phpinfo(); ?>
then try loading that page in a browser:
this should return information about your php installation, if it does not, there is a problem with your webserver.
you find this article helpful for setting up your testing server:
When you install MySQL, a user named root will be created automatically, during the install you will need to set the password for the root user.
in the localhost.php file, set the host to localhost:
$hostname_localhost = "powerstore";
Set the user to root:
$username_localhost = "root";
and the password t what ever you set it to when installing MySQL:
$password_localhost = "<root password set during mySQL Install>";
