If a website is currently selected where a user doesn't have admin access but view access, the UsersManager will show an error like this:

Instead of showing this error message it should maybe rather select a website where I have admin access automatically. We could do this easily in controller but then the idSite in the URL wouldn't match the selected idSite in the selector. I don't know if all code is actually fetching the idSite from the selector (I think they do). If they use the idSite from the URL in any way, we either need to change it to read idSite from siteSelector or perform a redirect when we notice user has only view access to selected site.
