Please note that there's a bug in Osclass v4.4.0, related to Users > Block/Unblock all items.

After you Block all items, you can't unblock them.
The unblock option doesn't appear and it still shows Block all items.

Thanks!

PS: please move the topic in the Report bug section.

Let me check, I would say there is no such button.

Good one.
Disable user and you will have that button switched.

Reason is, that following flow is expected.

For enabled user:
- first, you disable user items
- next, you disable user itself

Then, when user is disabled, and for some reason you want to enable this user:
- first, you enable all user items
- next, you enable user itself

Hope it is clear now
