The only place I see a reference to job-notification.php is on the dashboard in the javascript on line 219. If you remove that script does it still redirect to that page? I'm thinking that has to be doing it for some reason.
If you just type in the url: latest/dashboard.php?loggedIn=1 does it take you to the page? I'd debug it that way. It doesn't appear to be an issue with the login code.
