This problem is usually caused by not having this line in your footer.php <?php Loader::element('footer_required');
If you check in your theme folder you will find a folder named elements, in there is your footer.php file. Open it and make sure its there, if not add it, and you should be right as rain,
If you are still facing the issue, Lemme know.
