An unexpected release of UpdraftPlus has just been made, with exactly one change, only.
This release resolves a conflict with the popular “Simple Calendar” (formerly “Google Calendar Events”) plugin, if you were using Google Drive for your storage. “Simple Calendar” made a major new release a few days ago (a complete re-write), and introduced a conflict with UpdraftPlus. Update your UpdraftPlus, and all should be well.
