How can I wipe my UpdraftPlus settings?

If you want to remove all UpdraftPlus’s settings, then there’s a button down in the ‘Expert/debugging’ tab.

UpdraftPlus does not delete its settings, or your backups, when de-installed. This is because some users de-install and re-install (or de-install the free version and install the paid version) and don’t want to have to re-enter their settings when doing so.
