Here's the only real solution that doesn't involve chown everything. Place the following inside your <virtualhost></virtualhost> in your website.conf. May also work in apache2.conf
``` PassengerUserSwitching off PassengerDefaultUser "your-user-name" ```
Now check your error log. There should be no more error.
I don't understand why. [Passenger docs refer to this as sandboxing](https://www.phusionpassenger.com/library/config/apache/reference/#passengeruserswitching). Not sure what other consequences there will be.
