I am in a completely updated status with
Drupal 8.5.1 and all modules updated including:
Workbench 8.x-1.0
Workbench Access 8.x-1.0-beta1
Workbench Moderation 8.x-1.3
So I thought I would try and take the final step (I thought) in getting the states going etc.
Unfortunately, when I tried to Enable Moderation States for “posts” I ran into a major issue!
Here’s the result:
The website encountered an unexpected error. Please try again later.

Can you tell me where I am going wrong?
