I was working my site and I believe I deleted the main content block from the layout being used for the user login page.  When I try to login at user/login the page is blank.  Is there a way to reset things...maybe from the database so I can get the login block back?

Fixed the problem...added code to my layout template to manually insert the login block. 

<?php 
   $frmnm = 'user_login';
    $dfrm = backdrop_get_form($frmnm);
    print backdrop_render($dfrm); 
?>

This got me logged back in and I fixed the layout issue.
