Hi,

my system lately has developed bugs , when i make a sale using pos sale, instead of poping up the receipt page in the browser after a completed sale, it brings a blank screen . it was updating the sale until today it failed to even update the sale . I tried updating to the current version but its breaking many pages and users can not make a sale . I would like to move to the latest update without loosing any of my data.

Kindly advice
