 * hey jmckiernan86;
    can you (on staging?) re-update and then check with just CSS
   or just JS or just HTML optimization to see which one is causing the breakage?
 * my money is on CSS; the new version of the CSS-optimizer is way faster, but apparently
   it is also a bit more prone to crashes if there are CSS errors, of which I see
   one in [http://staging-healthbuff.kinsta.com/wp-content/uploads/elementor/css/post-1450.css](http://staging-healthbuff.kinsta.com/wp-content/uploads/elementor/css/post-1450.css)(
   at the very end you have a rule without a selector and the ending `}` is missing).
 * hope this helps,
    frank
