I’m running Nginx on Ubuntu 14.04. I have my website installed in the default /usr/share/nginx/html directory. My website works fine for several days and then the system automatically overwrites my websites index.html file with the default Nginx “Welcome to nginx!” index.html file. I have to go back and copy my website’s index.html file again in order for my website to work. I’ve had my website up for a couple of weeks now and this has happened three times. My website will work for a few days and then my index.html file will get overwritten. There is no method to the madness. Does anyone know what might be causing this to happen?
