I ran into an interesting issue and I believe I've fixed it now, however the settings that I changed shouldn't have been touched at any point since initially setting the system up. While rooting around in the database, I have seen columns that say stuff like "last changed by," but I'm wondering if there is anything more verbose than that. Looking at archived 3700d logs isn't feasible, as I have no idea when this particular setting would have changed. Specifically, the setting is for how gift cards are read by Micros.
