Well, here's the fix for those of you having this problem with Warp 6 Yootheme Themes, namely Cloud. Keep in mind this is probably considered just a temporary fix, I'm not too keen on doctoring themes...
The theme doesn't seem to be calling on the following scripts:
add-to-cart-variation.js, add-to-cart-variation.min.js
so I added:
<script type='text/javascript' src='http://yoursite.com/yourdirectory/wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.js?ver=1.6.6'></script>
<script type='text/javascript' src='http://yoursite.com/yourdirectory/wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.min.js?ver=1.6.6'></script>right before the closing body tag on template.php in the
wp-content/themes/yoo_cloud_wp/layouts directory. Next I fixed these two javascripts with lorsa's script. That did it...
