Roles for editing users Manage Options

Hello .

I’m using pmpro with Members plugin to manage an “editor” role.

The only way to give an “editor” the way to modify an user membership level is to give the “Manage Options” capability, but this give too many access..
the capability “pmpro_membershiplevels” seems to be the doog but not working for me ..

Ps : i use : “ACF” , “MailPoet 3”, “Members”, “FG Joomla to WordPress Premium”, “Paid Memberships Pro” and “SEOPress”

Can you help me ?

Thanks

Alexis
