Problem:

When you create a workspace with Nintex Workflow status runs on "error occured".

Reason:

The error in the list can be caused by the "Workflow Tasks". The Collaboration Manager detects "two" lists because of the space character.

Solution:

• Select Nintex Workflow Management in the CA.
  
• The name of the list can be changed in the "Global Settings"
  
• Here, the space needs to be removed -> "WorfklowTasks".
  
• Perform an IISReset. 
  
• Subsequently, the list in the template in question is to delete
  
• Disable the Websitefeautres the Nintex module and reenable.
