Hi there @netforia
There is an option in the Advanced settings to grant access to the Editor role and above.
But if you want to grant access to the Author role, you’d need to assign the edit_others_posts
capability to that role.
That would mean your Author role users would be able to access and edit other Author users’ posts (not Pages though).
If you want to do that, I’d recommend the excellent User Role Editor plugin for that:https://www.ads-software.com/plugins/user-role-editor/
Cheers!
