I use newest 1.0.3 version. I have tried Your advices and none of them works.

No it did not resolve the problem. I have newest version and problem persists.

I have no caching on the back-end.

I can confirm: there is a problem. I can’t uncheck.

I use this plugin and works excellent. Maybe there is a conflict with another plugin or with Your theme.
Maybe it is about php version. I use PHP 7.1.x and like I wrote before – works for me.
Check previous version 1.6.3

You are wrong. Quizzes are in the place. Basic question types are for free. Quizzes can be accessed from Course builder.

Advanced quizzes is additional paid plugin.

It was removed in 3.16.0
Now it can be accessed from Course builder.

I have marked it already as “members only” but not every member should have access to any file. Maybe at least any chance for /download/ part generated conditionally?

Or maybe any chance for /download/ part generated conditionally?

You are right. After saving settings there is no notice. THX

I have also updated to 3.0.1 and problem persists.

Looks the same or even worse(screen)

If You need some particular detail/info feel free to ask. I will try to help.

Looks like I have to wait. I will check after problem with analytics is resolved if everything is ok in the back end of my site.

I can confirm. After updating to newest version there are errors(debug file).
(I have removed some sensitive data/information)
