if this has been asked before I apologize.
Usually the advice for setting file permission in wordpress are folder
750 and file
640 with user and group
www-data. Based on my understanding if user and group is the same then if somehow outsider can access using
www-data he still can read or write,right?
so what's the point on setting up users and group as
www-data ? Is there security reason for this ? I think if file / folder is set as user other than
www-data then the owner permission can be useful.
