Hello there,
I am having problems with the quality discounts feature of the sales booster,
I am trying to offer discounts for my customers who buy above a specific quantity. I activated the quantity discount as soon as I did that the site is having issues if I log in as admin and at the same time try to open the store it says 503 service not available but if I log out of the admin it works perfectly. and also I can’t deactivate the quantity discount to see if it is the cause.
