Hey @mangelreynolds,
The issue with your installation has somethin to do with the Siteground optimizer plugin. I went ahead and disable it for you and your website is now working properly. On the other hand, Optimization plugins like Siteground Optimizer often combine scripts and reorder them and the common cause of issues as some scripts should not be combined, minified nor re-ordered. That is the case with our products, you need to exclude everything from Pro from any kind of optimization. Don’t worry, our themes are optimized out of the box so they don’t need third-party optimization.
Hope that helps.
