Well the old config.php file for mysidia adoptables should look like this:
PHP Code:
<?php
//Mysidia Adoptables Site Configuration File
$dbhost = 'localhost'; //DB Hostname
$dbuser = 'yourdbusername'; //DB User
$dbpass = 'yourdbpassword'; //DB Password
$dbname = 'yourdbname'; //Your database name
$domain = 'yourdomain.com'; //Your domain name (No http, www or . )
$scriptpath = 'scriptpath'; //The folder you installed this script in
$prefix = 'adopts_';
?>
Copy/paste this format to your config.php and change the values for each variables(begin with $) to whatever they are supposed to be in your old config file. Run the upgrader again and it should work.
