Thread:Extension talk:Flow/Uncommitted DB changes being unfixed by update.php/reply (5)

User:Ckoerner, unless you're seeing this error in conjunction with "Uncommitted DB changes", please file a separate bug or create a separate thread.

Can you enable logging and look for the exception in a log that gives more details?

And/or, in your browser console look at the Net tab and the error from the server may have more information in it. It sounds like Flow can't access the workflow object that it thinks corresponds to the Flow board. Does this happen when you try to edit the header of all Flow boards?
