[Theme Horse Support Team]

Hi Justin,
We found that you have customised the code. We always recommended you not to customise the code. If you really want to customise the code then first make the child theme of it and then only customise the code. Because while updating to our new version all your customisation code will be lost.

I also found that you have added some script on header.php which is affecting the navigation menu.
Just now i removed it this script from header.php because jquery.min.js is already loaded in our theme. So there is conflict and you are not getting the navigation menu.
Remove script from header.php
<script type="text/javascript" src="easybox/jquery-1.8.2.min.js"></script>
Now you can see that its working fine there.

Thank you!
