Add to cart problem with woocommerce/comet cache?

I have a site I’d like to use Comet Cache on. When its enabled the Add to Cart doesn’t cosmetically work. This is the apache log that happens when an “Add to cart” happens:

stanpacnet.do180.com-ssl_log:101.222.224.170 - - [03/Aug/2018:12:50:20 -0400] "POST /cm_ajax HTTP/1.1" 200 145 "https://www.stanpacnet.com/product/139ml-jar-96-pack/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0"

My problem is when it works I’m suppose to get a dynamic “Check” on the button to signify the cart addition happened. And the cart dollar value and count are suppose to increase in the navbar. This cosmetic check/dollar value change do not happen when comet-cache is enabled. BUT it does add to the cart still, so if I goto my cart I see what I just added. I’ve tried to “URI Exclude” all these pages including that /cm_ajax but I can’t get the cosmetic notification check/change to happen when comet-cache is on.

Anyone know why by chance? All plugins are up to date including woocommerce Version 3.4.4. I get no javascript error. Thanks for any help.

I get no javascript error.

Really? I tried going to http://www.stanpacnet.com/product/8-ounce-paper-hot-cup-stock-print-euro/ and, even before attempting to “Add to cart,” I can see the following errors:

yes, but those errors don’t impact the add to cart. add to cart is working fine now because comet cache is off. when I turn it on, it doesn’t (cosmetically) add to cart.

What precisely did you have turned on in Comet Cache?
