We found out that the Coupons module was no longer working because of a bug in the code, caused by it not handling coupons assigned to archived Staff members. We lodged a bug report about this, but was told “Even though we test our code thoroughly, we cannot guarantee that there won’t occur any issues in your installation due to the work of other plugins”, and we should “update <our> support package”. We then provided four simple steps to duplicate the issue, and our ticket was handed to the technical department to check it. The Tech guy was able to duplicate it, and a code fix came out in Bookly Pro 1.2. All up, it took 2 weeks (admittedly over New Year’s) but it did get fixed. Thanks, Dmitry!
