Js error “ImagesLoaded not defined”

Hi all,

Hopefully a quick one, I’ve installed the plugin and set up a gallery on the homepage for a site I’ve built but the images are greyed out and firebug is reporting js error “ImagesLoaded not defined”. The images open in a lightbox once clicked so the script itself seems to be running as expected but the error stops the masonry function from working as well. I’ve gone through and disabled and caching plugins I had installed just to check that there’s no obvious conflict.

Input will be greatly appreciated!
