Hey Micah,
I have checked your site again and your slider is now working fine.

This could just be a caching issue. I can see that you have temporarily deactivated the WP Fastest Cache plugin. When you activate it again, please make sure to regenerate the minified CSS and JS files. And then since you are using SiteGround, please clear your site cache in your hosting panel as well. The SuperCacher is developed by SiteGround exclusively for their customers. It increases the number of hits a site can handle and boosts the website loading speed. The SuperCacher includes 4 different caching options for maximum optimization of your websites. You can access the tool by clicking on the SuperCacher icon in your cPanel.

Hope this helps.
