Not defining function on line 59 as static triggers php error: [Strict Notice] call_user_func() expects parameter 1 to be a valid callback, non-static method Page::ShortcodeColumns() should not be called statically Note: PHP 5.5.12
Original example gives: Fatal error: Using $this when not in object context in E:\localhost\abscreensavers.com\mysite\code\Page.php on line 19
