Notice: Undefined variable: loginizer

I get this error with the latest version 1.4.4 when I’m on
/wp-admin/admin.php?page=loginizer

Notice: Undefined variable: loginizer in /wwwroot/wp-content/plugins/loginizer/init.php on line 804

I think its just your missing a global like you have on the other functions
So in init.php

// The Loginizer Admin Options Page
function loginizer_page_header($title = 'Loginizer'){

?>
<style>

becomes

// The Loginizer Admin Options Page
function loginizer_page_header($title = 'Loginizer'){

	global $loginizer;
?>
<style>

Hope that helps.
