Symptom: For one course, loading the Dashboard produces a STOP sign error with the text: "Unexpected Error. Please contact the system administrator".
If the Dashboard loads successfully for all courses but one, it may be a corruption of the underlying data file associated with the Dashboard. This can occur from a course copy or restore of a much older course archive.
We recommend the Blackboard system administrator (with system level access), go into the Blackboard server at the system level and rename or move the "lockdown_browser_settings_do_not_delete" file from the system level "PPG" folder for the specific course.
For example, this is a path on one of our test servers:
/usr/local/blackboard/content/vi/BBLEARN/courses/1/TEST002/ppg/lockdown_browser_settings_do_not_delete
where "TEST002" is the course ID of the course. Please be aware that the starting path will be different on your server and folder naming mighty be slightly different with the version of Blackboard Learn.
Once the system administrator renames or moves the "lockdown_browser_settings_do_not_delete" file, the instructor will need to navigate to the course and launch the Dashboard to generate a new underlying settings file and verify all the tests have the LockDown Browser requirement.
