New to Nintex, so this may be a beginner question. However, I'm having problem with my fresh Nintex Workflow. I made a workflow in a SharePoint 2013 environment, which is a copy from a working SharePoint 2010 environment. All actions are equal.


I got this (and other errors) in the ULS-log


Failed to create a control from assembly 'Nintex.Workflow.ServerControls, Version=, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12', class 'Nintex.Workflow.ServerControls.SiteActionsWorkflowMenu': The control with assembly name 'Nintex.Workflow.ServerControls, Version=, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12' class name 'Nintex.Workflow.ServerControls.SiteActionsWorkflowMenu' is not allowed for web at URL ''. The type Nintex.Workflow.ServerControls.SiteActionsWorkflowMenu, Nintex.Workflow.ServerControls, Version=, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12 could not be found or it is not registered as safe.


I followed the blog post Error: "Failed to create a control from assembly" and checked all the bullits. I have every feature switched on, license is installed correct, Nintex have been activated and so on. We have SharePoint 2013 Enterprise (and features switched on).


Looking at the images from the workflow, doesn't tell me much, and I don't know where to start looking.



(Sorry for the Swedish, but I've translated so you know what it should say )



I'm running the workflow as

  • System Account, setting (1) System Account and (2) User with contributor permission as approver
  • Regular User with contributor permission, setting (1) System account and (2) User with contributor permission as approver


The error is the same.


What are the next steps to solve this issue?
