Found it! Apparently clicking on ‘Continue on Error’ or ‘Stop on Error’ when nothing is script is selected will get you to the Workflow item where the whole script can be disabled or enabled. Very strange. Hope this helps someone else.
I am having the same issue. I have 3.2.0.916. The issue is still there. I have seen a couple of potential solutions in the forums, neither of which have worked for me. Has anyone any advice?
