Check Virtualmin -> System Settings -> Account Plans and if needed change from Automatic to Selected bellow. Or you can change this individually for each virtual server. Based what i read in Virtualmin docs if you keep on Automatic and allow creation of virtual servers the users will have full access to all options.
I just check and it looks like system information part comes directly from the theme. If this is true you could setup another theme for other users, prevent they can change it and then change in the code to not show that part. For example ask the creator of authentic theme (https://www.virtualmin.com/node/34315) what you could comment out from the code and in return you can make a small donation. It could be win-win solution just dont forget to apply the changes after every theme update.
That sounds like a bug. I’m guessing the new right page stuff is broken in some regard. The user won’t be able to do much beyond the usual, but the extra stuff shouldn’t be showing up. Has anyone filed a ticket about it yet? (I’m on my phone at the moment, so not really a good time/place for making bugs).
In the authentic theme it does not happen, just the default at the moment.
They ( domain owners ) can see that stuff in TOP anyway if they new how I guess.
Seems to be a lot of bugs at the moment
Surely you can see it for yourselves without others posting bugs all the time?
With regards to the package updates I can confirm that even if the packages are not fully updated it still shows as fully updated in the domain owner area.
