I followed every step in How To Install Linux, Nginx, MySQL, PHP (LEMP stack) in Ubuntu 16.04, as suggested by support, going first to the link of the initial set up and configuring my droplet security and i had **all **the results as expected in the guides. I have two ssh keys, one for root and one for my user, both working perfectly in Putty and Filezilla.
However, when i came to the very end of the guidance i did not see the page by zend engine, but when typing in browser radha.org.br/info.php, the file downloaded directly to my notebook, not showing in browser. (i had the google main page in browser and it just remained there).
