The easiest fix for this if everything was working properly before you moved the files would be to remove the first 10 lines of code in the WA_Globals.php file.
Delete these lines:
<?php
//need to run installation wizard
if(!file_exists('../Connections/installed.txt') && (!file_exists('Connections/installed.txt'))) {
if(file_exists('../install/index.php')) {
header('Location: ../install/index.php');
} else {
header('Location: install/index.php');
}
exit();
}
?>
Make sure you don't leave a blank line in the page. This code is looking for the installed.txt file in the connections folder and if it doesn't find it, it starts the install process.
I hope that helps.
