I just updated wordpress, wp e commerce, and my theme and now I am back to not having UPS functioning. I have added the / into UPS 20.php, as suggested by another user, and that had previously helped, but now no longer works. The theme I have is the theme that I have used the whole time, nothing has changed except updates.
The message I am getting is:
