Hello ocdhobbiest,
Thank you for your question about a "loading animation" displaying on your page. I can also see the animation.
When I use the Inspect tool in Google Chrome i can see the fancybox_loading.gif is being displayed when this plugin sends a request: http://*********.com/wp-content/plugins/etsy360plugin-extended_2_4_4
So, I recommend checking the "Etsy 360" plugin for known issues, or updates. It may also be an incompatibility with this plugin and other 3rdp party themes/addons.
Since this is a public forum, I marked out your domain name for security purposes.
If you have any further questions, feel free to post them below.
Thank you,
John-Paul
