Hey Dan,
Welcome to our Support Forum and thanks for writing in.
Our theme nor builders do not have an interface for CDN or any other kind of optimization. Most CDN setups work out of the box.
What you’re experiencing could be a problem with your web host. Judging by the screenshot, it doesn’t load the theme’s CSS and it’s probably not loading the required CSS of other plugins as well so your web host needs to check why that is happening. You might need to clear all caches including your browser’s cache.
It is important to note that the use of CDN and other optimizations could break the whole website and not just our theme. It is your web host or CDN supplier that will be able to help you with this issue.
Thanks.
