I don’t need help with my installation (from people here), I just need help understanding where the UI is pulling that variable from (IIUC, it is from configuration files on disk), how I can change it in the UI (IIUC, I cannot), and what that setting does/means (IIUC, it does nothing).
My default assumption when looking at a settings UI is that it will only include settings that are actually used by the system. However, IIUC, Discourse will simply list any setting that it finds in configuration files, whether that settings is used or not. In this case, my install ended up with an extraneous setting that isn’t used and the UI blindly presented it to me (not unreasonable, just unexpected).
Please correct me if I’m wrong about any of the above. If all of the above is correct, I can seek help elsewhere in getting that configuration setting removed from my installation.
