• Test nginx configuration fails:

  # nginx -t
  nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory)

  nginx: configuration file /etc/nginx/nginx.conf test failed

Cause

Plesk ships its own, pre-configured nginx.

The installed nginx package corrupted or replaced with incorrect one.
