Hi

The approval section of the workflow was working perfectly until:

1.  I added approval required in Versioning Settings of the Workflows Task list and then removed the setting.

2. Deleted a Status choice column.

3.  All permission groups were working previously.

I am not getting the error that Something has gone wrong when trying to approve any task.

I am assuming I need to reset the Workflows Task List to the default one without deleting the customised Nintex Form that I have created. 

You help would be greatly appreciated.

Regards

Renee
