Hello, when a user reaches the end of a lesson, and wants to review it, both clicking on the "Review lesson" link, both using the right side menu to return on any of the lesson pages, they meet this error.
The "More information about this error" link lead to an empty page with this title: error/lesson/cannotfindpreattempt
We tried to modify some settings about grading and of course we allowed to retake attempts, what can be wrong? It appears like a bug.
PS. If you exit the lesson and re-enter it, you can retake it without issues.
