Are you seeing a page that says
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in /home/trogarg/public_html/config.php on line 79
With the URL, it may just be that we don't allow URL based file access. I know we didn't before and I'm not sure if it is still that way.
For your second question, having intermediate instead of basic will not cause things to not work.
