Install Tool: "Default File and Directory permissions" should be green if ok
The recommended setup is still "group writeable" (0660 and 2770), which is why the default permission check will still output is as a notice with this text:
Currently configured as 0660.. Recommended: 0660. Make sure that your server environment supports this before changing it.
Change that so that if configured as recommended it is green.
Adds a text in case of group write/readable, that the group the webserver is in should only contain trusted local users.
