[Plugin: WordPress Post Tabs] HTTP vs HTTPS

There is an issue using Word Press Post Tabs on pages that are secure. They display but they do not hide. In the php file I changed the following line $pageurl="https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; to this

if ($_SERVER['HTTPS'] != "on") {
    				$pageurl="https://" . $_SERVER['HTTP_HOST']  . $_SERVER['REQUEST_URI'];
				}
				else {
					$pageurl="https://" . $_SERVER['HTTP_HOST']  . $_SERVER['REQUEST_URI'];
				}
