It looks like the paths that are on your include files are written out incorrectly. They should look like this:
<?php require_once( "../WA_Globals/WA_Globals.php" ); ?>
If you go to line 1 of your users_login.php page, does it look like that or something else? If it looks like something else, try downloading the files again fresh from the download center and upload those files to your server.
