Prior to LifterLMS 3.16.0 users were able to exploit a bug in LifterLMS that allowed you to “share” quizzes (eg have a single quiz used by multiple lessons) as well as share questions between quizzes (have the same question on multiple quizzes).

This was a bug in LifterLMS (from our perspective). When we released 3.16.0 we *fixed* this bug and the 3.16.0 database migration intentionally duplicates any quizzes and questions that are shared since it is no longer possible to share these elements.

Since releasing 3.16.0 we’ve had quite a few users note that they *did not consider this a bug but it was actually a feature* so in a future version of LifterLMS we’re working to figure out how to allow quizzes and quiz questions to be shared. However, at this moment quizzes and questions *cannot* be shared like they could in versions prior to 3.16.0.

I’m sorry for this jarring change. I wish that we would have realized how many users wanted to share questions before we approached this as a bug (we had a lot of reports in support of users accidentally changing a quiz in Lesson A when they updated Lesson B’s quiz (because they never realized the questions or quizzes were shared!). But we never had anyone say something like “I love that I can share quizzes between lesson!” In retrospect we know more than we did then.

I hope this explains what’s going on here and please let me know if you have any questions.

Best,

Hi @thomasplevy
Thank you for your answer.

Although I think it’s another case here. We didn’t share quizzes.

And did because of the deletion of that feature all lifterlms (that used shared questions) have double quizzes and double questions? Or is this something else, that’s not related to this?

How can I quickly “clean” my quizzes, so that there are no double questions?
Also when I try to delete duplicate answers i get error messages sometimes (see screenshot here).

Please help us fix this quickly.

Hmmm I’m not sure about that… A long time ago we used to recommend a 3rd party csv to quiz question uploader which we learned during the 3.16 upgrade actually created quiz questions in a non-standard format and caused some duplicates for users who had used it prior to upgrading. They fixed the issue after we became aware of it but any affected users would have duplicate questions like this. I don’t recall it creating duplicate quizzes but the duplicate questions happened.

Did you ever use a plugin like this to create your quizzes and quiz questions? If so, I think this might be what happened here.

I don’t recall exactly how we fixed it because it only happened to a small number of users and this was nearly 2 years ago that I was dealing with this in support.

To proceed I’d need to be able to inspect the malformed data in the database to see what the malformed question data looks like that’s creating these duplicates.

Since you have LifterLMS Stripe installed you have access to our premium support desk via your account at https://lifterlms.com/my-account/my-tickets

Would you please submit a new ticket there so we can share credentials securely and also bump this up in priority and find a solution for you.

Thanks,

Ok. As you don’t see a quick solution to solve this via database or so and have not had the case before, we will just delete all the duplicate answers in LifterLMS and hope it works fine afterwards.

As we tested it yesterday, it seems to run fine after deleting duplicate answers. So we just have to go through all the quizzes and clean them up.

Thanks for your replies,
Simeon
