WebUI not working after php7.2 update

Help
1

Hey there. I updated php on my LibreNMS server yesterday from version 7 to version 7.2 as recommended. However, I am now unable to load the WebUI at all. I’m using nginx as my web server and Ubuntu 16.04 LTS as the server OS.

Here is the output of ./validate.php on my system:

I am also seeing the following error messages repeated over and over again in /opt/librenms/logs/error_log since I updated to php 7.2 yesterday:

Note that we are using port 7000 on purpose.

Okay, I got it figured out. I needed to change the PHP-FHM section of my nginx site configuration to reference php7.2-fpm.sock instead of php7.0-fpm.sock.
