Themes

If the issue happens in other themes, then not a theme issue.  When in Essential I'm an 'admin' or switch role to a 'Teacher' then the gradebook setup does appear in the menu.  Thus must be down to the local role of trainer / training coordinator.  Without the knowledge of how they were set-up it is impossible to replicate and thus be in a position to debug and find a solution.  But as it is not an Essential or theme issue or something pertaining to one of my plugins, then I'm reluctant to spend time on it.
