"Object reference not set to an instance of an object"
I am getting this error when I want to create or manage a Nintex workflow on a library.
- SharePoint 2013 on-premise
- Nintex Workflow 2013
- Nintex Workflow license is installed this morning, and expiring in June 2015. iisreset is done on App-server and WFE.
- In another webapplication the Nintex workflow designer is working as expected.
Why is this happen, and how to solve?
Thanks in advance!
