Hi @apachevape,
It might be worth checking caching, do you have server side caching? Or running an aggressive caching plugin perhaps? Does it apply to logged in users too?
Typically all you need to do is create a new user, assign the wholesale customer role, then make sure your product has a regular price and a wholesale price defined.
Couple of things you could try after checking the above:
1. Login using a fresh Incognito/Private Browsing window and test again.
2. Goto WooCommerce->System Status, Tools tab, hit clear sessions to clear all the cart sessions. Normally this isn’t required but it might help.
3. Turn off your caching temporarily to see if the problem goes away.
Hope this helps narrow it down!
Cheers,
Josh
PS. Do you have any details about the JS conflict? Would love to know what it was exactly.
