PHP FastCGI Permission Issue - php

Question

I've installed nginx on a fresh Ubuntu 18.04 server. Its for an osTicket installation if that matters at all. I put all the files in the /var/www/html directory and setup my sites-available/enabled. But when I go to the site I get an Access Denied message and the error log shows:
2019/04/07 13:50:24 [error] 17708#17708: *1 FastCGI sent in stderr:
"PHP message: PHP Warning: Unknown: failed to open stream: Permission

Already made sure all directories from /var/www/html down have www-data:www-data and +x.

Answer 1

Well, I jumped straight to configs and other ideas. Forgot to KISS. For whatever reason, the files from the osTicket download came with 755 permissions on the folders, but absolutely no permissions on the files. Did a chmod 755 on everything and now its good.
