Hi,
I've inherited a MOODLE instance. This was installed originally as 1.9.0 than updated several times until it's current 3.3+.
One of the main problems I see is duplicated questions, so I tried to see how to normalize questions and question banks...
As first step I walked thru this: https://docs.moodle.org/dev/Question_bank_consistency_check, and found that I have nearly 3 thousands of question banks with invalid (deleted?) context.
I wondering what is the best way to clean the mess up... (I do have backups , so can be a bit hard on this)...
Regards,
Peter
