I've taken over as a joint admin for our whole confluence, and the other admin shows me listed as an admin, but when I go to certain sites I am getting messages that say "Contact your space admin." But I am supposed to be the admin. I tried clicking the link for access and I get the message "Access request unsuccessful - your request has not been sent". I'm thinking because the person who used to control this has left the company, but I need to be able to administer the whole of confluence. Please help.
