Enabling WP_DEBUG Undefined index 'notice'

Notice: Undefined index: HTTPS in /home/user/folder/wp-content/plugins/simple-301-redirects/wp-simple-301-redirects.php on line 143

Just a quick fix for you, as I was trying to debug something else and I saw this gem pop up.

Original:

/*** check for https ***/
			$protocol = $_SERVER['HTTPS'] == 'on' ? 'https' : 'http';

Replacement:

/*** Set the base protocol to http ***/
			$protocol = 'http';

			/*** check for https ***/
			if ( isset( $_SERVER["HTTPS"] ) && strtolower( $_SERVER["HTTPS"] ) == "on" ) {
    			$protocol .= "s";
			}
