We did an SharePoint upgrade from 2010 to 2013. Additionally we moved our SP webapplication which includes a recruitng workflow and of course we use NINTEX WF 2013.
Now all the moves are made successfully.
Everything seams to be there which we had before,
No Errors when we moved BUT...
Now I get always emails that workflow errored (not all wf's but some):
The WF has ended unexpectedly.....
. . .
When I start a new WF, there is no error message (first). But the following tasks obviously don't go out....
Something I forgot here I guess, but I don't know where to search.
What could I try?
