Missing icons/java

I recently install WP fasest cache on a new site I am building and now all the icons and java are not working on the shop page. If I delete the cache they will come back for a short period then they are gone again. Also much of the javascript is not working correctly after installing this plugin. I have used this plugin on other sites without issue….

How can I fix this

Site is at 1844fab.com, shop page is 1844fab.com/shop-2/
