one of my office 365 list workflows on sharepoint went haywire and could not be terminated. It was suspended and went on an deleted the workflow itself. This brought me two terminated workflows with a deleted association. I have since deleted the list the workflow was attributed to. However since then I cannot save or publish any workflows on this subsite (it works on other sites though). I get the following error:
Error publishing workflow. The request was cancelled by an event receiver.
