Masonry element won't load on the bottom of a page with caching on

Hi,

The Masonry element won’t load on the bottom of a page with caching on (wp-rocket) Everywhere else it does work!

Example: http://www.lightsinmotion.nl/shows/led-shows/visual-poi-led-poi-act/ when you turn on caching the masonry element at the bottom won’t appear. It only appears if you zoom in and out through the browser. Is there a fix for this?

I haven’t turned on caching for now because then the site won’t work properly. You can turn WP-rocket on under plugins.

Thanks in advance!
