BO Shows Blank page - Help

[responder]

BO showing a blank page, just out of the blue.

 

http://frontlinesafe.../store/adminfls

 

I have also noticed the cart in FO is being emptied when you click on it. More lost sales yay.

 

Shows the following errors.

Did you recently modify classes/Tools.php? Make sure that file doesn't have any blank spaces before <?php or after ?>

Thanks, I changed the date format, seemed to work ok initially. Replaced tools.php file. So will change date format again and see what happens.
