Sorry, thought I included this.
Nginx on Lightsail via Bitnami. Ubuntu 14.04.5 Nginx 1.12.0-2
New installation, nothing extra installed, no applications running.
Tried it via putty, winscp, filezilla and browser shell window.
sudo chown -R
Most permissions are 755
I'm new to using SSH, so my commands at the moment are monkey see monkey do.
If I'm told to use a certain command, that's what I do.
If it doesn't work I have no idea why.
