Edit Theme code to remove Login block

Hello,

I purchased a theme for a website:

http://ledleyfood.com

I would like to remove the login form block on the top of the page. I tried to remove the block in the block admin page but even though it is displayed as "none" the block is still displayed. My question is, how do I remove the block by editing the code? Do I edit the template.php file? Below is the template.php code if that helps. Any help is greatly appreciated.

/**
  * This snippet catches the default login form and looks for your
  * custom user_login.tpl.php file in the theme folder
  */
/*function phptemplate_user_login($form) {
 $form['pass']['#description'] = 'password';
 $form['name']['#description'] = 'username';
 $form['name']['#size'] = 10; // change the size of the username form box
 $form['pass']['#size'] = 10; // change the size of the password form box
 $form['submit']['#value'] = 'Log out'; // change the login button text.

 return _theme004_callback('user_login', array('form' => $form));
}
function  _phptemplate_variables($hook, $vars) {
 global $user;
 switch($hook) {
         case 'page' :
       // SUPER IMPORTANT: These rules prevent you from crashing your server :-)
       if (arg(0) != "user" && $user->uid == "0") {
           $vars['user_login_form'] = user_login($msg = '');
       }
       break;
 }
 return $vars;
