Error after Update
System.NullReferenceException: Object reference not set to an instance of an object. at Nintex.Workflow.ApplicationPages.Preview.Page_Load
Is it happening for Nintex Forms?
Try deactivating and activating the Nintex Forms features on your site collection
No, it happens when we try to open the Nintex Workflow History.
We have also problems to edit existing Workflows.
After Update on 126.96.36.199 everything is terrible
