PATH_TRANSLATED is not always set by default on every server, so it produces an undefined index notice. That in conjunction with your server's error reporting being set very high results in the notice being output to the page, letting you know the issue. However, since things were output to the page, the headers to redirect you to the login screen cannot be set after output has been sent, so it throws a warning error that it cannot do the redirect.
This has been fixed in the codebase for the next release, but for the time being, you can edit plog-globals.php by adding this line of code up near the top: error_reporting(E_ERROR);which should suppress any notices and only output errors, warnings, or fatal errors.
Beta3 is the latest stable version. We are getting close to releasing the next stable version (tentatively titled beta4) and that should be released shortly.
I had exactly the same problem and I added this line: error_reporting(E_ERROR) in the plog-globals.php
now I get this message:

I am newbie to all these and I guess by trying to just copy/paste the<em> error_reporting(E_ERROR)</em> directly from hostgator's public directory messed this up :(
