I installed Appointments+ on my page about 2 weeks ago. The page used to be on a subdomain, but I moved it to the main domain last week. Ever since then, Appointments+ has been extremely slow. I just deactivated it, reinstalled and recreated everything, but it's still slow. And I can't access the dashboard straight from my page anymore - it seems changing from a subdomain to a domain has broken my WPMUDEV account.
