What version of PowerCMS are you using? With the latest version of PowerCMS the globals file should look like this:
<?php
$WAGLOBAL_Site_Name = "Admin Site Title" ;
$WAGLOBAL_localRoot = "/PowerCMS folder/"; //relative path to your PowerCMS files on your local testing server.
$WAGLOBAL_remoteRoot = "/PowerCMS folder/"; //relative path to your PowerCMS files on your remote server.
// Admin Settings
$WAGLOBAL_Admin_UserName = "Please enter your admin username" ;
$WAGLOBAL_Admin_Password = "Please enter your admin password" ;
?>
