My wordpress network have 4 blogs. Eventually, one user can't visit his dashboard after login because strange no enough permission problem. I create a bad decision, provide him super user permission(it isn't large deal to us). Then him can click on his dashboard, however the old super user can't go to the site dashboard. I personally use the brand new super user account visit site dashboard, it display just the new account as super user, however the super user number is 2.
I checked the database, in table wordpress_sitemeta, the admin_user_id still indicate that old one, and the need for site_admins is really a:2:title"i:1s:5:"new super user title". Any idea?
use the brand new super user account, whomever it's, to sign in and visit network admin->user section. pick the older super user account and visit the profile page, you are able to grant that old super role back.
x Grant this user super admin rights for that Network.
