I have an approval workflow with at least two participants. The workflows still appear to be in progress but when looking at workflow history the workflows fail to run. the timestamp on all those failed workflows are the same 9/19 12:00AM. In some cases the first participant approves the document, the second participant can not because the workflow failed. In other cases the workflow was overdue but the first participant could not approve, or the approval task bar does not appear in the document panel when the document is opened. so again they can not approve. The workflow reports do not give me details about what is causing the failures.
An additional issue that seems to happen is that any data a user has previously entered gets deleted.
Can anyone help?
