Web config changes not working

Hello,

Whenever I try to make a change under Global Settings in the WebUI, it does not save when I leave the tab. An example is changing the graph type from PNG to SVG I change it, but it never saves. Below is the output of validate.php

====================================

Component Version
LibreNMS 1.52-33-g00b148dbd
DB Schema 2019_05_12_202408_create_mpls_lsp_paths_table (134)
PHP 7.2.17-0ubuntu0.18.04.1
MySQL 10.1.38-MariaDB-0ubuntu0.18.04.2
RRDTool 1.7.0
SNMP NET-SNMP 5.7.3

====================================

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

Note that config.php overides webui settings. Make sure it is not set there.

Otherwise, you may have a DB missing some entries. Try running php artisan db:seed

I have tried that and still getting the same results. I do not have these settings in the config file.
