Hi Donna,

In this case, it’s the older copy of jQuery that the theme is loading in the footer that is causing the issue. In the theme’s footer.php file, you’ll see something like this:

 <!-- Placed at the end of the document so the pages load faster -->
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

This should be removed. WordPress has a function that will load the jQuery JavaScript library when needed, and the above code is interfering.

Here is the same page with the extra jQuery library removed:

Since other scripts included with the theme will require the jQuery library and are likely not declaring this dependency correctly, you will likely need to add something like this to the theme’s header.php file just before the theme calls the wp_head() function. It will look like this:

<?php wp_enqueue_script("jquery"); ?>

<?php wp_head(); ?>
