SugarCRM 4.2 & Blank Pages

After installing SugarCRM, and logging into the admin interface, I was not able to lookup the user details (login --> admin --> User Management --> ). Looking up the code, it was using templates to render the pages. I am not sure what the error in coding was, but I added to the pages:
modules/Users/DetailView.php
modules/Users/EditView.php

the line, die(''); to the last line of the code. That fixed the blank pages.
