The issue you are facing:
Failing to delete a user.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
- Created a user to safely evaluate a external product using Webdav.
- Used it for 10 minutes.
- Decided to delete the user, by selecting “Delete user” in the User section
- Could not proceed. Received notification: “An error occured during the request. Unable to proceed.”
Also tried to disable user before deleting, also making sure user was not logged in from anywhere.
Still failing.
Side note about “An error occured during the request. Unable to proceed.”
The correct spelling in English is “occurred”, not “occured”.
