So I just put Appoints + on my site. I was clicking around trying some things to get started (no I did not read the documentation first, lesson learned). And now when I got to the "settings" link I get the message - "You do not have sufficient permissions to access this page." I am the only user of the site and am the admin. Can't figure out what I did because I think it was something on the settings tab. I did deactivate and then delete it and reinstalled in. Same thing.
