Http Error 500 on Ubuntu Server

Hi, I’m having trouble after updating our server. It’s an Ubuntu Server 18.04

I’ve checked but I can’t see anything wrong. It keeps throwing the http 500 error

This is the output of validate.php


Component Version
LibreNMS 1.51-6-g4c8e8b72f
DB Schema 2019_02_10_220000_add_dates_to_fdb (132)
MySQL 10.1.38-MariaDB-0ubuntu0.18.04.1
RRDTool 1.7.0


[OK] Composer Version: 1.8.5
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correc

I’ve run and it works wothout any warning or fail. I’ve also update all packages and restart apache service several times.

Is there anything else I can check?


Check the apache error logs for hints, that’s the only place you’ll find something useful since this error comes from the webserver.
