Fatal Error message on iFeature child theme

Hello,

This error popped up out of nowhere a few weeks ago, and I haven’t been able to figure out what is wrong or how to fix it. It says
” Fatal error: Call to a member function get() on null in /home/nthsolut/public_html/wp-content/themes/ifeature-child-theme/footer.php on line 25 “

Below is line 25 in the footer.php file:

<?php if ($options->get($themeslug.'_disable_footer') != "1"):?>

and it is a part of this code:

*/

global $options, $themeslug;

?>

<!-- For sticky footer -->
<div class="push"></div>
</div>	<!-- End of wrapper -->

<?php if ($options->get($themeslug.'_disable_footer') != "1"):?>	

</div><!--end container wrap-->

Could someone please help me figure this out? My website is nth-solutions.com

Thanks
