 * Hello [@salzano](https://wordpress.org/support/users/salzano/)
 * Thank for reporting this. We will fix the warning. But looks like your server
   has something wrong in the configuration. Is it local version ? Sometimes local
   servers has that options turned off

 * Not local. The paths wouldn’t have www/ in my local environment. I don’t remember
   which site’s log contained this error, but I’ll try to figure that out. Thanks.
