I have been working with the developer of Admin Menu Editor Pro and there is definitely a conflict.
He had me set the Roles in Admin Editor Pro to use other plugins control role settings. Then had me deactivate User Role Editor. This is consistent:
If Admin Editor Pro is active and User Role Editor is active role Editor cannot edit all users.
If Admin Editor Pro is active and I deactivate User Role Editor, role Editor can edit all users.
If User Role Editor, is active and I deactivate Admin Editor Pro, role Editor can edit all users.
I need both plugins, so they need to work concurrently as they did 30 days ago.
