Please update your theme again ( cornerstone is already updated so the theme should be updated as well ).
Once updated, please login to your CloudFlare please turn off JS and CSS minification under Speed section. Then purge your CF’s cache. And if you have the cache plugin, then clear and disable it as well before purging your CF’s cache.
Even if you updated your theme or plugins, it will still serve old files if you don’t clear the caches.
Plus, you can’t have two X theme. You must delete the old one and install the latest one (make sure to backup the old one). It must have correct folder name, and having two themes means having different folder name.
