Potential plugin conflict

Hi, Great slider. It works great on my staging site (I use wpengine for hosting), but when I copied to live, my Revolution Slider doesn’t load and the TWI slider doesn’t load properly (it just lists all the products down the page, not in a slider. However, this is only the case in Chrome. IE seems to work fine. wpengine suspects it is a plugin conflict, and perhaps a cache exemption is needed. I’m not a techie, so I’m not sure. You can see the difference here: http://www.rwlee33.staging.wpengine.com and http://www.designbykathryn.com Can you give it a look? https://wordpress.org/plugins/twi-woocommerce-gridslidercarousel-lite/
