Hello Nicholas,
Thank you for reaching out and I am sorry about the issue you are experiencing.
As per Woocommerce, it’s advisable to exclude the cart
and checkout
from caching and minifying in W3 Total Cache(this depends on the settings you have enabled)
So you should add /cart/
and /checkout/
in Performance>Page Cache>Advanced>”Never Cache the following pages” and in Performance>Minify>Advanced>”Never Minify the following pages” filed. Make sure to save all settings and purge the cache once the pages are added to the filed.
It would be great if you could share the website URL so I can check for any console errors.
Let me know if the provided suggestion helps!
Thanks!
