Change Administrator permissions in backoffice not working

[zirael]

Hi there, I'm having a bit of trouble with adding a new employee - I have added his administrator profile and he can sign in normally.

 

However, there is nothing he can see on the dashboard - it says he has no permissions.

So I checked them in backoffice, and there are none. Even though I check the items I need (I am a superadmin), the permissions won't stay there when I reload the page.

I really cannot give this user SuperAdmin permissions.

 

So, what can I do?

Thanks a lot.
