It looks like your user account doesn’t have sufficient rights.
Perhaps ask the original owner for an account with administrator rights.
I would agree, but my account is setup with administrator rights (Users=Administrator)
Are you able to do any other administrative things? Add users, for example? Do you see the Appearance or Settings tabs at all?
I’ve seen situations where a user account was just named “administrator”, but didn’t really have WordPress administrator rights, so make sure that’s not the case here.
Yes, I was able to add a new administrator ID, but that ID also has the same issues.
My guess is there might be a plugin active that’s keeping you from doing actual administrator actions, but if you’re not able to see the plugins, then that would be a vicious circle… :-/
