I am running URE on a multisite install. When I go to URE from the network admin, or from the main site admin, the select element that should allow me to choose a role to edit, is blank. There are no roles to select.
My site is behind a corporate VPN (i.e. intranet), so I can’t show it. But I am not getting any console errors.
When I go to any of the child sites I can select a role to edit. But the reason I bought the Pro license was to set roles for all sites in the network.
License key activation is not related to this issue.
Check if roles list is empty (not empty) at the “Users” page “Change role to:” drop-down list and at the “Role:” at some (not yours) user profile page.
I suppose your main site may lose roles record somehow.
I’m still working on this issue. I see in the database that the wp_usermeta table has some odd meta keys, such as aa_user-settings, aa_3_user_level, aa_4_capablities, etc. The prefix on my database is wp_ (wordpress default), not aa_. Is there a reason that there would be some keys prefixed with aa_? Or could this be why my user roles are missing?
 I also see an aa_user_roles key in my wp_options table. That’s the options for the root site. Is this correct?
There is no visible reason for ‘aa_’ prefix inside permissions related database records until it may stay from the older data imported from the other database with such ‘aa_’ prefix.
These articles describe how WordPress stores it’s roles:
1) Single site;
WordPress multisite stores user permissions inside a single database table ‘wp_usermeta’ in assumption that database prefix is ‘wp_’.
So look what ID your user has and try to get all permissions records related to this user with query like:
SELECT * FROM wp_usermeta WHERE user_id=1 AND meta_key like '%capabilities';
and look if a record with ‘wp_capabilities’ meta_key value is there or it is not.
If it is not try to rename ‘aa_’ to ‘wp_’ and look if it will help.
As always, it’s a good habit to make a fresh backup before any manual data change.
