The plugin script files and inline declarations are completely missing from the home page. I see your site is very heavily cached, that is very likely the issue. Make sure to clear all layers of cache – page, minify, asset, CSS, JS, CDN, cloufrlare, wp rocket and your browser cache as well.
Once everything is set, the script files should be picked up by the cache and served.
