I have a problem with saving my Nintex WF. I just found a similiar Porblem in the community, but the solution didn't work for me:
This error only appears on one Sitecollection.

What I tried:
- deactivate/activating Nintex Wf feature on site/sitecolletion/webapplication
- When feature was deactivated - remove folder NintexWorkflow
- Reinstall Nintex in the Sharepoint Server
- Creating an new Content DB for Nintex
Have you any Idea?
