The only way to output a HTTP header reliably in the backend is in the admin-pre-header action - and it only exists in GetSimple 3.1.
In all other actions and filters some HTML has already been output and you will get this error message.
The only way it would work is if output buffering is turned on in your PHP installation - maybe this is the default for PHP 5.3+ or at least your installations.
