KB1117 - OU Wiki Group Mode Error

The following error message appears when trying to view/edit an OU Wiki in a course using a Forced Group Mode:

"error/Sub-wikis is set to 'One wiki per group'. Please change Group mode to 'Separate groups' or 'Visible groups'."

Here's how to fix it:

1. Turn off the FORCED group mode in the course settings.
2. Add the "separate groups" option in the Wiki and save the change (this was previously unchangeable because group mode was being forced).
3. Turn back ON the FORCED group mode in the course settings.
